Reproduce:

  1. Create table Tasks, make some entries
  2. In Tasks, add a Status select list column, make some entries
  3. Create table Projects, make some entries
  4. Link entries in Tasks table to an entry in Projects table
  5. Expand a row in Project
  6. Make sure to customize layout and “Display this column as table”, save
  7. Back in the expanded Project, use sort and group by Status
  8. Change the view to Board
  9. Press the green button with the plus, add a entry

That entry is not visible in the Status select list and cannot be deleted. Work around is to delete the column to clear and make a new one.
