LCR lock out

Recently and for no apparent reason a message appears as we enter donations " this batch is locked by .............". Anyone else having this issue as no one seems to know how to resolve or even why it is happening. It only occurs when one individual logs in to start the procedure not when they act as secondary signatory. Once batch is locked there is no way of unlocking or deleting. It is causing great problems for all concerned.

I see this every time, but from memory I just cancel the message and the process continues without further issue. I can’t remember exactly what I do, but it doesn’t delay the process.
