If a single comic gets a large number of updates the Updates page has issues. Note how page 1 only displays the one comic, with it spilling over to the second page despite plenty of other comics having recent chapters as well:
That's not a bug, that's how updates works from recenttly updated to oldest updated, combined with the limit of the amount of chapters that you could see in the settings, I know, it's annoying when someone made a bulk release, but is not a bug
