Unfortunately, after reading this thread, I was hoping for some good news, but this bug happens to me ALL the time. It occurs in every project I work on, regardless of the computer or version of Vectorworks I use, and has been doing so since 2022. This issue reoccurs over and over and no one from tech support has been able to help.
The only solutions I have found that seem to fix this problem involve deleting all the wall peaks under AEC, or trying to manipulate the wall in some way. This could mean moving the wall, connecting another wall to it, or copying the wall into another blank file and then back again. I sometimes also try saving the file as an older version and then reopening it in the latest software. The updating process seems to rectify the issues. These methods have proven helpful, but this bug is extremely irritating and consumes a lot of my time trying to rectify it. Consequently, I often end up on these forums, searching for answers. I would really appreciate it if this issue could be fixed.
