Any Help on why my power level increases on its own to 5?

I have a 2019 Giant PRO E + 1 orange E MTB.
After my dealer upgraded my software I noticed occasionally that the power level , on its own , increased usually from 2 or 3 to 5.
I actively decreased it, pressing the decrease button while riding. Sometime it would stick there for 20 minutes, and then increase to full power.

I just had a dealer tune up and it increased immediately to 5. Pushing the button 20 times it finally decreased (temporarily for a minute) to the lower 2 or 3 power level. So it is getting worse.
Did the update to my firmware cause this?

(The button mechanism works fine when it finally comes off the full power, sometimes taking 30 presses. Once down it clicks fine unless I am pedaling.)

What is the issue? Why did it originate? Repair approach.....please?

I bought my 2020 Giant Stance E+ last july and never did any update, never been to the shop and i have no phone.
It is fine. A few times the assist changed but it was winter and my big gloves touched the button.
I read not all updates are improvements i guess they will correct it.
I would consult with my LBS.
