I am also running into this problem, but it is even worse than MrOnak's (or he has the same thing and hasnt noticed). Using the Food/Mineral options does seems to do nothing when focused on the ship/station. However, much worse than that is if you have either running while focused on something else, then the stations food consumption skyrockets. I switched to another craft for 10 minutes and lost 3.5 days of food. Everything else calculates normally, but the food just goes insane when using either of those. I have tested it both on the 2.5 hydroponics and the cupola with the same results.
