title: Merge button is disabled after all the checks passed on Github
body: <p>Github is blocking all the pull requests from being merged, even though all the checks passed. There is no configuration for reviewer approval on the repo.</p>
  
  <p>After all the checks passed, it still shows <strong>Required statuses must pass before merging</strong>. If I close this PR and reopen it, then the button is enabled and I can merge it normally. Does anyone know how to solve this?</p>
