Auto stop or Pause if silence not working

Hi was recording a podcast I experience these bugs
Auto stop if silence or pause feature in WaveLab 11.20 seems to be not working.
Auto start works

I think it works, but you might have to select proper settings:

Interface is Zoom F6 48/32 Float. (works fine with Reaper)
I also have Motu Ultralite5 but it does not do 32Float.
These are my settings (below)

will try a clean install and update
If nothing works I will go back to Motu Ultralite5 which worked fine previously.
