Not Able to Drag issues in a Kanban Board

Question

Suddenly not able to drag issues on Kanban Board to certain columns (not all of them).
However, transitioning issues via Workflow buttons is possible. 
Please note that the kanban board is for a JSD project.
As shown in capture 1, I can not move it to "Done" or "Canceled".

I tried updating the add-ons since we recently moved to a new version of Jira.
Tried re-indexing. Still not working.

Hi Pete,

Thank you for your reply.

Yes, the workflow statuses are correctly mapped.

What confirms this also is that the dragging was working before, and stopped without changing any workflow statuses, or board configuration.

Have you checked the board configuration to ensure the workflow statuses are correctly mapped to the columns on the Kanban board?
