ok, let me see if I can explain this correctly. On our active sprint board we have 6 swimlanes. (TODO, IN PROGRESS, TESTING, SME APPROVE, PO APPROVE, and DONE). Some of these swimlanes have 2 drop zones when you go to drag an issue to the next swimlane. For example if I try to drag an issue from IN PROGRSS to TESTING the TESTING swimlane has two zones(ready for test and Testing). I know this has something to do with either workflow or workflow scheme but I can't find a clear answer to how and fix this so it only has 1 landing zone.
