See screenshots. Notice how I have 4x400 = 1.6k storage for potatoes and veggies, yet the amount is displayed as if it is 421/800 (potatoes) or 0/0 (veggies). Comparing also with my other food markets, it looks like the storage space in food markets is only counted if it's not empty, which seems like a bug!
To reproduce easily, place a food market, configure a food type that you're not providing, hover over the food item so the statistics tool tip pops up, and notice how it says you have 0/0 instead of 0/400.
Reproducible in B470 and B479.
