Beginner CPAP Struggles (Repost)

Apologies to anyone who commented on my previous post, I'm still getting the hang of OSCAR.

I have been on therapy now for around 6 weeks but I am still having an AHI on average between 10-14 AHI each night. Have attached some data from OSCAR from last night. Is there anything I can be doing to help here? I am currently using a ResMed Airsense 10 with an F20 full face mask. I also have quite a large beard which I fear might be playing into this.
