Unknown shows in 'Up Next'?

I noticed a couple of anomalies in my Up Next list today, I checked the time/date and I have no recollection of watching or marking those shows as watched at that time.
Is there any other way of me seeing where, maybe what IP/device, I marked them as viewed from.
I’ve also noticed some episodes that I definitely marked as watched, now showing that I have not watched them?
First time I’ve noticed this in 4 years or so.

Please open a support ticket and we can take a closer look how the plays were added. For the missing plays, please try resetting your browser data and see if that helps (assuming you’re seeing the issue on the web).
