You have uploaded five planet mods, which are not supposed to be used together. It sounds like it would be much easier and less confusing for everyone if it was a single mod instead, with a start-up setting of which planet to actually load.

Yeah, my intention is to have a pack that picks between them to load. I'll go back and remove the any planet start requirement, so that if anyone wants to load multiple (for say a team-based multiplayer, everyone gets their own start) that they can work together there too.
