Just confirmed this does not appear to be a problem in ArchiCAD 20 (build 5025.)
(The project in the screenshot above was started in 18, took a bit of a "vacation," and came back to life today.) Still, we don't have time to migrate the project today into AC 20 (we need to send some drawings out the door asap) so if anyone knows the solution, we would appreciate it!
