I don't know if your issue is still an issue and if this solves it, but it's worth a try and works fine for me:
Instead of adding the General Width and Height parameters, add the Width and Height parameters from an actual window object, these are called A and B.
(On the second image with the loaded parameters you should see the length icon instead of the arrow.)
edit: I only see one screen shot image from the ones I tried to share. Oh, well... If you have questions about how to add parameters from objects, let me know.
This issue should have been fixed in ARCHICAD 21 update 5021 (fix #230091), and the released version of ARCHICAD 22 (3005).
Please make sure you have the latest build installed (7000), and if you still have this problem, then send me a PLA and a picture of where this issue is, so that we can take a look at what we might have missed.
