Table Visuals not showing for only a couple of users (no RLS)

Hi, 

Since a week or 2 some of our end users are experiencing problems with openen certain reports. Everything in the online report is working fine except 1 or 2 table visuals. Those table visuals are completely empty (see print screen). Slicers and filters are working fine but the visual itself just doesn't load or something. We have no RLS so everybody with access to the workspace can see the entire report. It has happened in more than 1 workspace and more than 1 report as well.

But somehow for certain people the visual is just not showing anything.

We have tried refreshing visuals, refreshing browser, deleting cache/cookies, logging out and in but nothing seems to work.

Is anyone having the same problems? How did you fix this?
