Why am I receiving notification emails for old topic posts?

[Animebryan]

Lately I've been receiving notification emails for old posts on topics that I created, but when I click the link & it leads me to the topic, there's no new post. It's referencing an old post like a few months ago. Is there a reason this is happening? Some sort of glitch in the notification system? I'm including a screenshot of the latest email, addressing me & the date, as well as the topic it's referring to.

I do also recall seeing similar emails for old topics that hadn't been replied to in ages, although I didn't give it any thought.

That's odd, I don't have email notifications enabled, but I could've swore the receiving notifications for old replies in threads part has happened to me at least a couple of times in the past.

I also got the same email notificaiton problem for some reasons, but apparently there were no replies in the topic.
