Hello @Rich Stubby
Thank you for reaching out on the community and telling us about your issue. I do apologize for the issue you're having. It sounds like inside of the register itself there may be a transaction that is stuck in a pending stage. You can double check by going to your payment register and looking up the payee. From there see if in the status column if you're able to find a pending transaction. If you are I'll leave an article down below on how to delete the transaction. You will need to add it back manually so I would recommend creating a duplicate of the transaction prior to deleting it.

Once you've had a chance to try this let us know if you're able to get it deleted. If not we'll see what we can try next.
Thanks,
Quicken Francisco
