Wrong calories consumption calculation displayed

I have selected hardest difficulty and so my dupes consume 2k calories per day each. I have 3 dupes, so that makes it 6k calories per day.

I have discovered a new planetoid, which appears on the top right corner and allows me to see issues in those planetoids. One of the issues states that that the food reserves are low and there is information that 3k calories are being consumed per cycle. This is wrong, it would be 3k if I had normal difficulty.
