As far as I can tell, this question was not answered
Is this a split design db? Each user runs their own copy of frontend?
This would not be the first time that someone posted a similar problem only to eventually find that each user was attached to a different be table. Of course this would not be the case if it was a shared front end, so please answer the questions posed so that the focus of answers can be more precise.
I checked the MS Access Security and can confirm that the users that can see the data and myself are in the same user group.
What does this mean? I see by your info that you use A 2013 but are you saying the problem db is an older version and uses a workgroup (mdw) file?
