OBS Studio - plugin load error

I'm getting this plugin load error:

The following OBS plugins failed to load:
decklink-ouput-ui
Please update or remove these plugins

Looking at \OBSPortable\App\obs-studio\obs-plugins\64bit one can find two files that aren't present in OBS: decklink-ouput-ui.dll and decklink-ouput-ui.pdb. (n.b. the missing T in output)

Additionally, there are two other files that are present in OBS: decklink-output-ui.dll and decklink-output-ui.pdb.

Can these misspelled files be safely deleted?

Also, I'm getting these failures in the log file:
