Q: One of the teams in my organization has a problem with some stories not showing up on the storyboard and I cannot see any mistakes in the fields (they have correct planning level, team and sprint). 22 out of their 60 stories are showing, so is there perhaps a limit on the number of stories that can be on the board? Do you have any suggestions for what I can look for in the data?
A: There is no limit to the number of items to display. When you change the team to one that has their own process defined, the status previously selected is no longer valid. If you are in the TeamRoom, and the TeamRoom is filtered by that team, if you select the "Backlog" panel to display, you should see those stories display on the Backlog panel.

What Impact does defining a team process have on my instance?
