Message already in admin action

Hello,

One EO message is stuck (TBDL) in single stack PI version with below error, i thought removing user lock (from NWA -> User Sessions) will work and release the locks from the message but it didn't work.

Resending the message failed, due to: java.lang.Exception: Message already in admin action or locked by message version editor.

Not sure what else i can check? Any inputs will be appreciated.

Thanks
