@Foxgood Other tags are consistent, like if a series is shounen, you can't just change it to seinen, except for Publication status or rarely artists info which need to be changed but they are still facts. On the other hand, things like missing chapters depend on the scanlators. As MrIncognito said, chapters published in parts screw up the missing chapter system, scanlators like sssss who translate whichever chapter he wants to troll people, or anthologies where scanlators only translate certain chapters/independent stories and leave out the rest would also put a series into "Missing chapters" category, even if, in fact, all readable chapters are up on Mangadex. I guess it all comes down to me personally don't mind accessing the series, and see "Missing chapters" tab, check to see what it was about and then decide to read it or not.
