Bed Size issues since Prusa Slicer 2.9.4 update

When using a 235 x 235 PEI plate (left over from othe rprinter) in the past the machine recognized the correct size after changing the bed setup in Prusa Slicer.
Now with 2.9.4 the printer always moves the bed completely backwards and goes to search the bed in the very front n left corner - actiually where even is no heat bed to find.
Here it fails and the lovely machine complains that there is noch print bed to find - lol...
Well, if I select ignore, it suddenly repeats the bed setup in the correct area.
Bed size change done - no difference
Physical printer with 235x235 bed size added - no difference.
Zero XY changed - no difference

It seems something changed since lat firmware version. Unfortunately in the not so funny direction 🙁
At least I can work with it, but it's nasty to always select 'Ignore' on each print.

Does anyone know what I'm doing or thinking wrong?

Sorry guys. Was not related to PrusaSlicer.
Went back to firmware 6.2.x on my MK4S and everything runs fine. So, if you like to us a different build plate of smaller size just make your settings in PrusaSlicer under Printer (general - printbed (first entry)) to whatever size you have and DO NOT upgrade the firmware to 6.4.x - so far 🙂
