First of all, we not see in interface of OrdaSodt Joomla CCK
the world "Titel". Please hint to us where we may find it.
Sorry, for me not clear why need add special field "Title" for metatags, You as admin may add MetaTag Title in every Instance(WE already have special field for this). Only if you need add this to frontend?!
You mark field as "Title" in "add instance layout" - only if you not wish every time fill "special field for title"
And Please check "Title" we use also for add product to car.
Also Please check for Google - more important what you have in H1, H2, H3..
