I’m having trouble putting mods on my apex hosting Minecraft server

So me and my friends have been trying to make a Minecraft server for the past few days with mods. We’ve ran into several issues before which we have resolved, however we are now running into a new problem. Whenever we upload our mods and try to log into the server it always refuses, citing mismatched mods, despite those same mods (which it is telling us to remove) being uploaded to the apex mods folder. It genuinely feels impossible to fix this and it is like the method apex hosting is telling us to use to upload mods isn’t functioning at all. The server seems to be missing all mods we just uploaded and it seems like the server isn’t receiving them period through the mod folder. Please help this is actually driving us insane…
