Dreamstation incorrect flags - voluhar - 02-19-2023

Hello all!

Recently I switched from System One to Dreamstation, got my Dreamstation 1 as part of Respironics recall. The machine was manufactured after the recall date and that doesn't worries me.
What worries me is lots of hypopnea flags while I'm still awake. Just like the ones on the uploaded OSCAR screenshot.

During those events(4 hypopneas, 1 OA, 1 RERA) I was completely awake. It also makes a lot of flags which are inconsistent with the airflow.
Is it possible the machine is malfunctioning or is it possible the flags are misflagged because I switched masks? 
I went from PR Amara to Fisher and Paykel Evora FFM because I have horrible issues with my nose bridge.

Thanks in advance.
