When you edit a box (for example, moving a Pokemon) in paginated mode, then exit edit mode and change pages, the box you edited becomes locked in place and won't change. You need to refresh the page to fix it. In the example image, boxes 5, 9, etc are inaccessible because I edited box 1. EDIT: Additionally (and probably the same root cause), after editing the Pokeball/Shiny markings don't appear to be working, but do actually show as having worked when you refresh.
