Hello
Thanks for reaching out to us and I’m really sorry you are having this issue. ?
Unfortunately, this is a known issue so I linked this thread to the bug report so the team will let you know when the bug fix is released in a future version.
The issue seems to be only when Event Update Authority is set to “Import events but preserve local changes to event fields.” I know it’s not ideal, but in the meantime if setting another option works for you I would encourage to do so.
You can get to that setting in Events > Settings > Imports tab under the Event Update Authority and you should select one of the other options to prevent the issue.
Let me know if any other questions.
