Read marks

[Mordenheim]

Hello. For some reason, the read marks disappeared from both Follows page and manga page.

Edit: And they don't come back even after re-reading the chapter.

@Mordenheim They work fine for me, are you sure the manga is set to 'Reading'?

Yes.
I've tried unfollow and follow. Nothing change. I will try something with my browser.
