I'm not sure if this is a bug or intended

So when i sort folders by "Last modified", by default the order is inverted without enabling "Invert" in sort options, i don't know if that's a bug or intended. Also i would love if sorting for pictures is different than sorting for folders, because when i sort for folders i want to see the latest comics i added first, but when i go inside the comic folder i have to change the sorting from "Latest modified" to "Name / Number" so i can read the comic in order, that can be frustrating having to repeatedly have to do that.
