While food shows up on Yor plants, it is irrelevant. The stat has to stay around, however, because it becomes relevant if the planet is conquered. If you mouse over your population, you get a tool tip that shows current population/max population. It would be nice if you could find max pop of a Yor planet without having to check a tool tip, but it isn't a bug per se. 

While i understand the value of food needs to stay around the info should change to he appropriate field for the yor.

As long as the value remains in the mai. Screen it will be cunfusing to people playing the yor

I don't see why it would be so hard to give it a different name when the Yor are inhabiting the planet, and switch back to "Food" if the planet is taken over by another race.  Also, I found a "Wild Grain" tile on another planet that gives a population boost.  Why would the Yor care about Wild Grain?  I assume if I build a Power Matrix there it would get the same population boost, but maybe for the Yor those resource tiles could also be named something different?

Thanks!

were not talking about getting rid of food for iconia 

what we are asking for is appropriate information show up for people playing as the yor. 

the amount of food available is useless info to the yor so why have it on the main planet screen and at the same time bury the vital information of population cap for the yor

No, it's just a UI change. The food stat will still be there, it just won't be visible to Yor players.
