One of my teams has a planning board connected to a Service Desk project. When moving Tasks between future sprints, they do not show in the target sprint on the board although if you click the "View in Issue Navigator" icon for that sprint, the Tasks do show up in the filter as expected. The field sprint = the correct sprint (i.e. the one I moved it to) and the filter column for sprint shows they're in the sprint. They just don't show in the proper bucket on the board.
I've checked the board filter; it's as wide open as can be. It specifies only project = my project name. I checked all the column definitions, there are no unmapped statuses. I checked field permissions, filter permissions, project permissions, everything looks fine.
Has anybody experienced this too? Any suggestions on a fix?
