Additional context

Of note, this is an ERD for tables that do not actually exist in the database.

[KaylaSolace]

Ok, yes. looking at the generated SQL this seems to be from renaming tables or columns. the links seem to keep their connection to the table visually but lose what they are actually connected to when the name changes. thus, deleting them requires renaming the table and or column back to the existing name.

potentially may be solved by solving #7903
