Put the Omni Colonny techs at the top of your file (well, at least above the regular colony techs) and you should be fine.

I think it's also a good idea to give each Omni Colony their own family number 6001-6003 for the dual ones, 6004 for the triple one.

PS: Oh, and make sure they are devided by an empty line. Not right after one another like in your posted code.
