Salutations amyjolo,
We’re going to recommend some basic troubleshooting to begin with. You’ve let us know that you’re using the TV app, but we’re not clear on which device you’re using it.
The first step would be to restart your device.
Restart your iPhone
Restart your Apple Watch
Restart your iPad
Restart Apple TV
Shut down or restart your Mac
Next, please also check any other device(s) that use the same Apple ID and see if they are showing the progress in an episode or watched episodes. If they are, we’d next like to have you sign out of your Apple ID, not your entire iCloud account though, and sign back in.
For iOS and iPadOS you’ll do that in Settings > your name > Media & Purchases.
For macOS you’ll do that in System Settings > your name > Media & Purchases
Thanks.
