ERDs - ER links remapped when review Notes

I am creating an ERD of an Informix database. I manually map the ER links that are not maintained in the database and add notes to the tables. When I review the notes, the ER links are moved from the fields I assigned them to to other fields in the table.

Is this normal behavior? It is frustrating to have to undo and redo the manually mapping to fix the issue!


I have reproduced this problem also and I will write a bug report on the issue.
