Bases spawning underground

Hey, I've got to the point where I've got the bases working (for the most part) but the bases seem to always spawn either underground or underwater.

I'm guessing there's something I need to change to fix this but I can't find it for the life of me. any assistance would be appreciated, cheers.

Found what i think im meant to be changing but it is not working.

heya. what bases are you referring to? tier package bases? different bases? the only solution for the latter is to adjust the height in the profile for the base or recopy it at the proper height. package bases should never have this issue.
