Holy crap. I just saw this last report.
Leaks aren't the issue at all...be it mouth breathing or whatever...your leak graphs are well within what is quite normal for your mask and your machine...actually minimal excess leaks are occurring.
Central Sleep Apnea brought on by the addition of cpap pressure used to treat Obstructive Sleep Apnea gives us that nice Complex Sleep Apnea diagnosis.
And while yes...sometimes it will fade away on it's own I don't see that happening in your case because it is so pronounced...so I have my doubts as to how much "give it time" will actually help you.
Watch this video...it explains a bit what and why some people develop centrals with cpap pressure.

You don't have much choice in the matter though...your doctor is in the driver's seat here.
I don't see this being related to mouth leaks or tape or not taping or anything but being plain old complex sleep apnea popping up.
Using Flex might make it worse but I don't even think turning Flex off (which you wouldn't like anyway) would help all that much.
And you aren't limited to centrals caused by high pressures...you are getting just about as many at the lower pressures of 8 ish as you are getting when the machine goes higher.
While miracles can happen and with time those centrals might stop happening....even if it did I suspect a very long time and you are having way to many centrals to just let slide by.
Light a fire under your doctor's butt...he said a couple of weeks...don't let him stretch it out for very long.
I predict a different machine in your future is going to be needed and sooner is better than later.
I may have to RISE but I refuse to SHINE.
