Hi, I am having a really strange issue, basically, since Thursday 2 users are struggling to open a project document correctly but one user is able to open the document correctly and use it fine. They are all running the same versions of office and patched equally. I have tried uninstalling, ccleaning and reinstalling project on one of the faulty machines but still having no luck at all. It is a really difficult situation to explain but basically the drop-down options aren't working for one column. Now it wouldn't be a problem to recreate the options, we tried this but after closing and opening the document a couple more times the problem returned on 2 of the 3 machines that use the file. I have tried restoring a couple of versions of the document, one from Thursday when it was working and also I tried as a test restoring the oldest version of the document in shadow copy but they both had the same problem. If anyone could help it would be most appreciated. I have also attached 2 screenshots to try and explain the situation a bit better.
