BP Thumbnails are corrupted

Today for the first time I noticed problems with the BP thumbnails. I have a bunch of BPs that consists basically of a static mesh and a light source, and when I edit a BP then other BP thumbnails, which I dont even work with all of a sudden begin to show a mishmash of pictures that aren’t even in those BPs. It is as if the BPs acumulate images from other BPs with which I work and show them in random combinations.
Each of those BPs in the picture has only one static mesh, yet they show a whole bunch of meshes from other BPs
