Thumbnail mixup in 11.0.4 (bug?)

The new update 11.0.4 makes it possible to decide that some images can be displayed at a higher resolution. I noticed when editing some of these in SAB that the thumbnails are (become) mixed up (see screenshot)

Having just changed the display size for the journeys of Paul, the Holy land image’s thumbnail has also become the thumbnail of Pauls journeys. Double clicking displays the holy land image correctly, but after resizing the thumbnails that are displayed have been mixed up. (see screenshot)
