CMS single reference > To rich text within symbol on a collection page

Hi There,

Can anyone shed any light on why i can add a rich text field and connect it to the CMS in a collection page - But i cant connect a rich text block in the same way in a symbol on the same collection page.

On this page the massive menu in the footer (rich text) and the main top menu (symbol > collection item > Rich text ) are pulling from the same source but to get it to work i had to use a collections list in the symbol.

Someone please put my mind at rest - been driving me nuts : )
