Stuck on iOS 13 beta

Basically I installed the iOS 13 public beta on my iPad 6 several weeks ago. With the release of the stable release, I wanted to uninstall the beta version and get the public release. I uninstalled the beta profile on my iPad, but when I check for new updates, it says I’m using the newest version of iOS, even though I still have beta things such as the feedback app. Any ideas on how I can get the stable release?
