Looking for help with Respawn Ship Mod

Hey all, I'm making my first attempt at a mod; a custom atmospheric respawn ship. I've been able to get it to work to spawn in space, but when i added the lines to spawn it on a planet it no longer shows up in the spawn menu. I want it to add to the list of default respawn ships so I've left those enabled. I'll post my file below, can anyone point out what's gone wrong? Thanks in advance!
