I do not know for sure, but I assume our automated submission checking is following over because the original author of the code is not a searchable GitHub user.
It looks like “WP Freelancer” is not searchable on GitHub. Can you confirm if this is a deleted account or a bot?
It seems you may have hit an edge case we did not account for, and I will need more info before suggesting the fix.
The rules outline you need to be the primary author and in the majority of th commits as well. Your repo seems to qualify, but I am providing the context to explain our check that is failing on those commits.
