If the subfolders are not immediately after the mod name folder (for example;Mods> MariTheButterfly >MariTheButterfly >Events, Fetishes, Images, etc.) the mod might not work so move the inside folder out(the one that would lead you to the events fetishes images) out to the mods folder
Idk if that makes any sense
For a better explanation you can use the page with the list of mods
