When I copy and paste the “Addition” module (after deleting the inlet/outlet text), the “A” & “B” reappear!
This is detrimental, because I may be using variables entitled A and B somewhere else in the document. The other modules do not do this.
In fact, when I was only using a trial version of Rhino with the grasshopper add-on, I think this did not happen.
Could this be the result of a problem during installation?
