Playlist records line inputs, but no USB/MIDI devices

[BLESZ]

Hey everyone,
For some reason I'm not able to record USB/MIDI instruments directly into the playlist anymore. Only Line inputs.
The mixer tracks do show that there is sound and I can hear it also but after selecting the recording option Audio, into the playlist as an audio clip. Nothing is recorded.
When I select Notes and automation the notes are getting recorded
As mentioned before, recording via line input in my AI works fine.
This happens with all VST's used via USB/MIDI devices. Never had this problem before.

Any idea which setting is causing this?
I'm using FL Studio 20.9.2
Steinberg UR44C (Tested all the input options)
