This can happen if the issues in question were updated by some plugin, without following all the necessary steps. Or the status was directly changed in the database.

You will have to fix the discrepancy in the database I am afraid!

I'm pretty much with Jobin on this one - sounds like a very broken addon or external process, and something you need to remove immediately. 

Except before trying SQL, I would try changing the workflow scheme for project TA - that might be able to repair it.
