Problem
The users can't find and select the sprints in the sprints column. Even though the sprint is visible, it shows the "Sprint currently not in this plan. While this sprint isn't in this plan, it's appearing because it's assigned to issues in the plan" warning and an EXT next to the sprint name.
Cause
This is caused by the issue sources of the plan. Sprints are a feature of a board, and they are loaded into the plan automatically when a board is chosen as the issue source.
Resolution
Navigate to the Issue Sources in your plan configuration and choose the Board as the issue source.
