I don't know if this helps but whenever I encounter a bug, I make sure that the latest Hotfix/Update is installed for my Archicad version.
In the case of AC23, Update 4 (Build 7000) was dropped only a few weeks ago.
If you have not done so, try installing it and see if it solves the issue. These updates usually contain many bug fixes.
