The inactive team is still displayed on the Program Board in Jira Align
Summary
The feature that is not associated with an inactive team is still visible under the team in the program board. As a result, the inactive team also appears on the program board.
Solution
Along with performing the below-mentioned steps, the Inactive team must be removed from all the Stories/work items and also from 'Add/Remove from Board' in Program Board 'Team Target Completion Sprint' for the Team and Features to not appear in the Program Board.
Once you click on 'Add/Remove from Board' for the Feature, you will see multiple Teams along with the inactive team. You have to remove only the Inactive Team from the list and click on Update.
Sample screenshot as below:
In Jira:
Move all assigned items back to the backlog

Make sure no member is allocated to the team
