Support Interface not selectable

Hello,
my problem in BambusLab-Studio: i cant select the Support Interface-Filament.
The Pulldown is grayed out
Bambulab-1

Ok, if he would use it anyway. But no !

Here is the slicer answer:

Bambulab-2

I use the version 1.10.1.50 and the current firmware version on the P2S.

This problem occurred to me after the last software update.

Does anyone have an idea how I can correct this?

Best regards

Subei

The image looks like support pla is loaded on ams slot 4 and selected ( cant be changed/used ) try removing the filament from the ams and see if it changes back to a dropdown box

not sure if it will be applicable , but worth a read
