Skip duplicate chapters cause incorrect skipping with less common chapter numbering

[Eplutt]

Steps to reproduce

Enable skip duplicate chapters
Read a series with less common chapter numbering (in my case "Sx - Episode y", see pictures)

Also replicated with a custom local entry consisting of:
P1 - ch1
P2 - ch1
P2 - ch2

Expected behavior

This is what happens with skip duplicate chapters turned off

Actual behavior

In the case of the custom entry it reported that there were no more chapters after "P2 - ch1"

Mihon doesn't have the concept of Volume/Season/Arc and whatnot so this is kinda expected
