Graphical Problem with filters

Hello there, 

I have a problem with the filter pane. Every time I set a filter and choose one of the values, the filter turns completely grey.

This is how the filter area looks before I set one of the options:

This is how the filter pane looks after choosing to filter only for "Area". My mouse was still hovering over the Area, words, thats why I can see them in the grey. When I move my mouse away, the "Area" also is not seen anymore.

The error probably was caused because we worked together on the data file with different Power BI versions. But I now have updated my Power BI and it still does not go away.

I would appreciate any help!
