I have a client that's billing from November 2, 2020 is stuck in "Proof" stage. I doesn't show up on the screen when I go to run off other client bills. It only shows up when I go to Billing Assistance and the Bills. I can check mark this particular bill, but can't do anything with it. How can I get it out of Proof stage? We have new bills that need to be run today and sent out and it needs the last billing reflected.
