I am sorry for the experience, thank you very much for sharing the problem.
I found similar issues corrected by our updates, so I would like to ask you to confirm that both users are using the latest build.
Another option is to move a fill on which the dimension should be and then undo this action. This process will trigger a recalculation on the fills, so that will unhide them from an affected view.
If this does not solve this issue, please send us the support package from both users. They will help us with the investigation. You may find how to do it here: https://helpcenter.graphisoft.com/knowledgebase/25480/
I will send you a link to the shared folder in a Private Message.
I will be looking forward to hearing from you!
