Series marked Completed keep getting unmarked

[Davincie]

Just as the title says. I like to mark series completed when im done so i can remember if ive already read them. I keep noticing series ive already read no longer being marked completed, but just going back to the default status

@Davincie Late reply but 'Completed' behaves by unmarking all of your read markers and just visually displaying all the chapters as read. It doesn't actually mass-mark things as read. It's intended to be used on series that you're done reading, not series that you're still reading but are caught up.

Being able to mass-mark read icons or change your follow categories is planned, though.
