RAMP settings on Dreamstation 2

For the past few weeks the RAMP pressure setting on my Dreamstation 2 has been changing without me or my provider making any modifications to the setting. It started off a 6, changed to 8, and this week to 10. Since my pressure range is 8- 12, starting at 10 is not good. I know how to change the Ramp setting. I am trying to determine why that is changing by itself.

Thank you.

Any chance you might be inadvertently touching the display when turning the machine on or off that could bring up the Ramp icon which can change the Ramp pressure? There is a 'Confirm' on that display, but the Ramp pressure appears to be changed and hold the new setting without pressing the 'Confirm'.

Any curious children with busy fingers in the house?
