Filters reset themselves: what to do to keep them?
In my Library, the filters (see image) on the bottom of my window, reset themselves overtime. In the image below you now can see: flags, stars and color labels... but - I think when I close and re-open LR - they are all gone and I manually have to bring them back, which is annoying. I recently re-installed LR and since then this happens. Before it was all good and they stayed visible, even after closing the application.
Also, the arrows, left and right, to turn images 45° aren't visible anymore and I just can't seem to find how they get implemented in that bar again.
Can anyone give advice on this?
Thank you!
