The albums on my desktop iPhoto won't transfer to my iPad mini iPhoto

I can't figure out why my Mac desktop iPhoto where I have multiple albums set up with pictures won't transfer ALL of the albums I have set up. I have a Mac laptop with iPhoto that transfers what I have it set up to transfer just fine to my older ipad. Both the Mac desktop and ipad mini are new w/in the last year.

When I plug in my ipad mini to sync with mac desktop, I have my itunes sync settings on iPad mini to sync with iPhoto, selected pictures, albums, etc & include No Events &have the albums I want transferred checked off in the Photos section.

It seems like there is transfer from ipad mini to desktop, but doesn't seem to go the other way. Any ideas?
