Multi-wythe solid brick VS Multi-wythe hollow brick

What is the difference in bounding strength for Multi-wythe solid brick VS Multi-wythe hollow brick? Is the Multi-wythe hollow brick considered to be grout filled?
When choosing a sold brick my anchorage fails in "Bond" with 303%. If I switch to hollow brick the value goes down to 45%. Please see the file attached.
I reduce the Vx to 1lbs and the anchorage still fails (with solid brick). It doesn't look right.
