Also when I go and checkout just to test every page is showing the above info. ?

I get this above info as well on the page when I go to checkout submit all the fields.

Install fresh joomla/vm some-ware someware and compare databases tables/columns.

Also before that in Extension manager under the database tab you may find button that fixes database , if you see it click it.

Last note is that you make sure joomla/vm are updated.
