Dave,
Yes my profile is up to date and I run SU 2021.
I just did a search on “automatic fixing” and noticed another thread that said starting in SU 2021 this feature can not be disabled. Turn off Validation / Auto Repair in 2021
In that thread, @colin of the SU Team, requested to see a file where the automatic validation cuases a problem. Maybe my mention of his name here will get his attention. Otherwise I will post my file as a reply on that thread. I have seen this issue before, and likely only in 2021.
Do you have any other suggestions ?
