Program selector jumps back to the top of the list

Hello there

A new and annoying bug came with the trial version:
In the program selector when I click on an entry, the displayed values jump back to the top of the list. This makes it quite difficult to use this function.
Also, it is no longer possible to navigate in the list of programs with the arrow keys on the keyboard.

Cubase 12 on the same machine works fine.

Please advise. Thank you.

Thank you Jorge. Yes, this is the same with the cursor keys, but in the trial version the mouseclick also gives this frustrating behaviour.
Investigating further…
