We have seen similar issues in the past. I am not 100% sure but I think we resolved it by going to File Open, click on the drawing, select References and double clicking on the wrong reference and then selecting the correct one. It has been a quite a while so the steps listed might not be exact but it is somewhere to start,
I am familiar with this problem you are describing but unfortunately doesn't fix my problem.
Having a bit of a play around it seems that the drawing 230783 and part 230977 were imported into EPDM with the drawing reference already in place at version 1, this means that rolling it back doesn't help because as soon as I check it out to remove the data out of the drawing, checking it back in makes it go to version 2 (or 4 in this case).
