Screen Time Glitch

Hello, I was wondering if anyone can help me with this issue? Lately I’ve been very aware of my screen time and have decided to dial it back a bit. I deleted the Twitter app a couple days back but to my surprise I had used it for 7 hours and 47 minutes today? This is obvious some type of glitch as this is my only Apple device and there is no way someone has my iCloud log in and used the app on a different device. I was wondering if this is maybe the apps spyware? Or some data leftover monitoring me? To be honest I’m not quite sure so I was hoping someone here could explain. It’s kind of annoying bc I do look at Screen Time to monitor my usage and this is definitely going to throw all of my numbers off. Thanks in advance!
