MFP food nutrient content wrong?

I hav been relying on foods on this site to check poteins and carbs and other nutrients but when i added beetroot to my food log a noticed it has no iron at all!! I thought Beetroots were a great source of iron...My Nutritionist sister recommended it.

I searced for foods they seem to be high in iron I have relied so much on this site and am all wondering whats up!!
