Unfortunately this looks to be a bug with the hacktoberfest system that's affecting PRs that were still under review after hacktoberfest ended. I've contacted the organisers of hacktoberfest about this and they acknowledge its a flaw in their logic but I'm still waiting to see if it will be fixed.
It may help if you report the problem at their email: hacktoberfest@digitalocean.com and maybe they will do something about it if more people say its affecting them!
