unread thread reset

[Pano]

I'm having trouble with the "unread" button. It seems to reset by itself and so I miss a lot of new posts. Too bad, as the button is very handy.

Other forums with the same software I'm on don't do this unless I exit the forum, and that's a setting somewhere. But I can't seem to find the settings here.
And search turns up nothing.

Where is the setting or how is the reset happening?

Can you refer me to the specific "unread" button you're referring to? Cheers.

Hi Jason,
It's the one next tho the thread title. Threads with unread posts show in bold and have the button. Clicking on the button takes you to the 1 unread post in the thread. See screen cap below.

On this forum threads get marked as read even tho I have not read them.
On other forums with the same software I have to read the thread, or mark it read. Optionally all will be marked read when I exit the forum.

Here a lot gets marked read before I see it. Can't quite figure it out. Thanks!
