1.7 Orbital Improvements Don't Function Correctly

I'm noticing a lot of inconsistencies when it comes to orbital improvements. All of them seem to function correctly on core worlds, but to piggyback on the thread about orbital prisons, most of them don't function like you would expect them to on colony worlds. 

Here is the list of orbital improvements that when built on a colony world, have no effect on the core world. I can't help but think this is a bug or an oversight. 

1. Colonization center (+15% growth) - does not apply to core world.
2. Orbital prison (-20% crime) - " "
3. Atmospheric Cleanser - (-10% pollution) - " "
4. Recruiting Station - (+2 growth) - " "     

There may be others that are not listed here. It's possible that some of them are supposed to be exclusive to core worlds, so should not even be an option for colonies. In any case, the mechanics for all of this doesn't make much sense. Some clarification and standardization of mechanics is needed.
