Food Diary Question

Hi

I am trying to add a food to my diary by the creating a new food option as couldn't find what I was looking for on the database but know the calories however it is not bringing the section up for me to add the brand name, description, serving size etc. When I click on add food and then create a new food it is bringing up a list/table of everything that I have had since I started MF. Can anyone please help with this? If I log onto MFP on my mobile it is giving me this option but not when I log on via my computer.

Its only my second week with MFP and I am still finding my way round the site.

Thanks Sharon
