Profiling Rack Tuner always on "G +3X"

Hey there!

Last week i made 2 Software Updates to my Kemper from a very old version.

After the first Update, the tuner startet "working by itself".
It's always jumping very fast inbetween "G1 +33" to "G1 +36".
The problem is also there while tuning the guitar. Thats annoying.

This didn't change with the second update to the newest Software version.

I tried:
Other cables
Moved the Kemper away from my desk

Any idea what could be the cause of this issue?

Thanks for the reply!
I just did a "soft reset":
Holding SYSTEM button while turning on to Tuner Mode.

Didn't work BUT

i plugged in at the front input and found the tuner to be working perfectly fine.

So it just happens at the rear input for some reason.
Same cable/position/guitar - just a different input jack.

Maybe the rear input just "broke"?
Or any other suggestions?
