Hi @erikj79 , is this situation possible? I mean if we have a branch named 'release', in the first commit, it added a new file 'a_new_file.txt', in the second commit it added a new file 'a_new_file2.txt'. And we have an edit branch, in its commit, it added a new file 'a_new_file.txt'. Then we create the backport incorrectly with the hash of the second commit of release branch. So the backport is not clean. After that, if we correct the hash to the first commit of release, the check will not run again and the clean label will not be added to the backport.
