What causes this error? ElemenetId cannot be deleted

I’ll run into this error occasionally, and it’s just vague enough to me to keep me from pinpointing the cause. Can anyone elaborate on this and if there’s a possible solution?

I’m trying to create a Generic Model Face Based family in my project, and the family component is throwing this error.

Can you provide your About info as well as an example file to look at?

Does switching Element Tracking mode to replace and back again clear it up?

See if the error occurs when you attempt to insert this object as a generic model, face-based family into a project.
