Chapter Bug?

[KMoore]

I was reading Dekisokonai to Yobareta Moto Eiyuu wa, Jikka Kara Tsuihousareta no de Suki Katte ni Ikiru Koto ni Shita, I pressed chapter one but the chapter number on the reader menu is 4. The other chapter one works fine.

@KMoore Are you using legacy reader?

@Yatsuki Nope normal one with dark-slate theme.

People aren't supposed to upload two versions of the same exact same chapter (by number) by the same group, because things get weird like this.
