When the user creates a drawing he doses the following steps

1. Creates a sheet adds the part and information needed and saves the sheet
2. The user then checks in the file
3. He then does a save as and renames it as his new drawing.
4. Deletes all the old views and tables, and adds the new parts and tables as needed and saves.

He can see in SolidWorks all the references are gone but there not gone in EPDM as seen below in the picture. Even after several refreshes. some time the refresh happens 5- 10 min down the road other times it doesn't. This concerns the user that something is still linked and makes him try to chase down where the link is and there is none.  Is there anything we can do to make this refresh faster (is it a refresh problem?) or is this a bug?

See attached pictures for detail (they would be to small if I pasted them in the window) The user created the file names for me :/
