How things might have been handled in early versions I can not say since I never really got into using vbGallery myself always been a PhotoPost Pro license holder here.
vbGallery 2.5 code branch at minimum is almost 4 years old so how we display the statistics in vbGallery are the way they are, The Product has its own stats section for some time now.
I would think if you want them to display in the
vb part you would probally have to create a plugin for such an action.
