It's not weird or a bug, it's how it works. You must have been level 8, where Riven has 76 base AD. With +24 bonus AD (possible with flat AD Marks/Quints and on Offense tree build), that's 100 "total" AD, but Valor uses bonus, not total, which explains your shield.

If you went and bought a Long Sword, you'd notice Valor go up by 10 points.
