Sync issue - error - how do I fix it?

Question

When I try to sync to cloud, it doesn't seem to complete. I get a message that says "the reference source has been deleted; I have attached a screenshot of the message. It gives me no solution. How do I fix it? It appears to cause one bank account to not sync. Please help.
 Thank you.

That appears to have solved the problem! I no longer get the error message and the missing account now shows up on my mobile. Thank you so much
