Duplicate set of cellular data settings

I have an iPhone XS Max with iOS 12.

I have something really weird in Settings > Cellular. In there, I scroll down to the Cellular Data section to see the apps that have cellular data turned on or off. Usually when I scroll down I get to the end of the list. Sometimes, though, I can keep scrolling and there's a second, duplicate list with the exact same apps, the same MB/GB usage, but some with have different On/Off settings.

What's going on here?

I captured a video of the phone showing the issue as I scrolled. Can't upload here so this is a link

Here are a sequence of screen shots of the page as I scrolled, but the problem is more obvious in the video.

Thanks,
