For some reason when I try to merge a pr with gh pr merge from my development branch into master I get the following error:

Pull request #1 (Initial Commit.) can't be merged right now; try again in a few seconds

I am able to create and merge pr's from any other branch except into master. I have to go into the Github each time to commit the merge. My master did have a protection rule on it, but I took it off to see if that had any effect and it did not. I'm fairly certain that I have been able to merge into master before but I started having this issue more recently.
