The data from your sleep study suggest mixed apnea (with both obstructive and central components). Your treatment with a regular PAP machine appears to be helping with both. That's a bit uncommon, so good on you!
I should have done this first time around, but I just looked at that double OA moment on your SleepHQ chart, and both of those events look to me as though they happened after arousals.
You asked whether your events are "legit," meaning events that occur during sleep. We can see the arousal breathing ahead of many of your events. Arousal may mean a short wake-up, or it may mean you're shifting from a deeper stage of sleep to a lighter stage of sleep. We don't really have a way of telling which from the machine's data.
I tentatively conclude that the main issue you're having isn't so much your apnea events but is instead the arousals. I wish I could say there's a way to determine what is causing them, but there isn't.
I also wish there were an obvious change to your settings that would be likely to help. I worry that raising your minimum and/or maximum could bring on more CAs, so I'm reluctant to suggest that. The same goes for EPR, which might help with your flow limitations. I hope other forum members will chime in here!
You didn't include information about your O2 levels from your sleep study; do you have it? One thing you might do is to get a recording O2 monitor just to make sure your O2 levels are where they should be.
I would also recommend that you talk with the doctor treating you for ADHD to see whether your medication can be adjusted, in case it contributes to your arousals at night or your early-ish waking time. Before you started PAP, some of your ADHD-like symptoms may actually have been symptoms of poor sleep, so it's worth reviewing the medication now that your AHI is much lower.
One last question: did you have a titration study as part of your diagnostic/treatment work-up? That would be a study in which they put a mask on you and tried you out on various settings while you sleep. For people with mixed apnea, a titration study might also include emulation of several kinds of machine (regular, bi-level, and adaptive servo-ventilation aka ASV). If you didn't have a titration study, you might ask the sleep doctor about whether that would make sense. I'm not convinced it'd help if your basic problem is arousals, but you never know.
Finally, here's some information about sleep and light, which could conceivably be connected with your difficulty in staying asleep as long as you want to.

have been on APAP for around 5 months now, slowly improving, however nearly all my events are central apneas, some even whilst I am awake. Just wanting to know if these are legit central apneas or is the algorithm worse than I thought? Also any tips on sleeping longer, now I'm on APAP I'm usually wide awake after anywhere between 5-6:30 hours.
I have attached a copy of my sleep study from earlier in the year. I also have the added distinction of having ADHD so I take Ritalin first thing in the morning for this, usually feel pretty refreshed after 5-6.5 hours sleep. I work breakfast radio and can't remember last time my alarm went off which is usually set to 3:30am, On a typical night put CPAP on around 7:30-8pm asleep within 5 minutes, could wake up anywhere from around 2-3am. Not sure if the report will open properly if not will try send another way.
have attached last night's numbers, have been hovering around the 5-6 ahi mark the last 7 days. Still learning my way through understanding the charts and what to change, my breathing seems to be normal until random CA's which up the pressure and then I seem to have more once it goes up. Would it be worth lowering the pressure and maybe switching to fixed? Currently set at Auto 5-8 with auto ramp.
