Tried restarting revit. Still get error.

Ok, So if I click Modify in APL and then Cancel, Then Click select all. It works.

Believe I solved this one... Turns out I was forgetting to check for duplicates after making changes.

This was a bug in 2021, and will go away in 2022 release. It will only happen if you have unnumbered nested points, which isn't very common since most functions will cause them to be assigned a number.
