Since the beginning, there're many problems in Tag system. Some problems can be solved by delete manga then mark read & re-tag again, some can't solve by ourselves.
it's *sighs.. it's just frustrating me, especially when my obsessive-compulsion is on the works. thanks for the info kyozana, i need that (so i'd know when to give up lol)
this is weird. i discovered that i can sort my list through tagging them but it's probably an hour and the tag has not appeared yet?
also, i have been cleaning my manga tags and there's some abandoned tags that are still persistent even when i deleted the manga and re-tagged.
