Hi,
Thank you for the report and I am very sorry about the issue!
First, I would like to ask which Archicad version and language are you using? Please make sure that everything is up to date before continuing to the next step! I encounter a similar one with the release version of Archicad 23, and the bug was fixed in the first update.
Is there anything special about this file? Like is this containing some special elements, or was it migrated from a previous version? Maybe an Open & Repair process can help with the issue. Can the problem be replicated on a brand new file?
Have you tried what Ling suggested?
Looking forward to hearing from you!
Best regards,
Minh
