Hi,
Thank you for sharing the issue and I am sorry about the experience!
If I understand you correctly, you are using a custom door with a custom marker, or is it the default ARCHICAD Door/Window Marker? Or are you using the label Door Window Stamp?
Anyhow, I tested the issue with a default door, D Marker 23 and Door Window Stamp 23. After changing the ID using Element ID Manager, the stamp and marker automatically updated with the change.
I'm wondering if you could share with me a screenshot of the situation that you're having? If it is possible, a small PLA would be great in order for me to experience the issue myself!
Let me know if you need a secure link to drop your file!
Looking forward to hearing from you!
Best regards,
Minh
