You're welcome, BigRED.
I hope the tech support has a solution for you.
If I get something that isn't working as I think it should, I open a new project file and start from scratch. If that doesn't work, I restart the whole thing. Yes, that should not be needed, but being a tester of our software, this is the best way to check if something is reproducible, which is an important step toward solving it down the road.
My best wishes!
