Board disappears from Project when adding Rank

[Vivian Tang]

I have a Project with multiple scrum boards. When I added rank to one of the scrum boards based on a query filter, it removes the board from the project. What am I doing wrong?

Boards don't really "belong" to projects.  It sounds like you've made a change to a board which might mean the board no longer fits the criteria for being the default board a project might show to users, but you should be able to just select the board again from the drop-down on the left at the top of the panel.
