Am I crazy? Additional Projectiles question.

Is there a hardcap on additional projectiles for grenade skills, specifically explosive grenade? I'm firing 6 grenades, but I think I should be firing 7. With the Gemling and its Advanced Thaumaturgy, the bonus quality modifier says "Fires +2 projectiles" under the alt view. However, the normal text reads "Fires 2 projectiles". There seems to be a error between those two texts. Shouldn't the skill without any other modifiers be firing 3 grenades as per the alt view? The normal does not mention additional, it just says "fires 2 projectiles".

I tweaking over here thinking I'm being robbed of an extra grenade.

Edit: base skill fires 1 grenade, cluster bombs passive +1, bombard crossbow +1, multishot +2, bonus gem quality +2, but im only firing 6 total not 7? Am I tweaking? So maybe its not the bonus modifier that isnt working, but maybe one of the other sources for additional projectiles.
