BUG: cubase compressor doesn't show side chain signal cubase 9.5.41

this happened inexplicably today. new instances of the cubase stock compressor do not show incoming side chain signals on the gain reduction meter, making it a pain to use. my old instances show their side chain signals no problem, just today new instances seem broken: they show the signal from the channel itself rather than the channel triggering it.

any help would be appreciated.

aaaaaand it’s working again, for the time being, all by itself. terrible software
