Sorry about your trouble!
I have checked it with R21 and S22, it works here.
I hope that the developer can have a look at it soon. This week was kind of busy with NAB C4Dlive. I hope that makes sense.
Until then, where is it installed, what OS, etc.
Perhaps reload it, delete all previous versions.
Fingers crossed. Thanks for your patience.
My best wishes, stay safe, stay healthy.
