Masonry Anchor Design Discrepancy between Profis and Design Tables

Hello,

I'm finding a discrepancy between Profis and the Hilti design tables when running a calc for an anchor into masonry.

For a 3/4" dia. KH-EZ with 4" embedment into solid grouted masonry gives the following results...
Profis: Va = 2,432 lb
Hilti load tables = 3,040 lb

The two values are off by exactly 25%. Can you help me understand where the difference comes from. See attached for my results.
