Barometer - FW 20.29

Hi!

Quick question about built in barometer on FR965 running on stable firmware 20.29.

Today I discovered that graph is... strange?

This is view from last 48 hours.

But altimeter works, counting floors also, it doesn't matter if Im running an activity or not.

Also tried cleaning sensor hole on back of device under running water (didn't put anything inside), but nothing changed.

Any got clue how to make this work again?
