Sivir E Interaction with Camille E

So I played Sivir against Camille and apparently blocking the E of Camille with my Spellshield only blocks the stun and not the damage. Also Camille gets the AS Buff of her E. In the Video it's clearly shown that I Spellshield before the Camille's E hits me, thus blocking the stun part but then I still take its damage before her Q kills me. Server is EU West and I can provide the Replay if neccessary.

I am not sure if it's intended that Camille gets her AS Buff because the spell is blocked but I guess it can still Count as her landing the spell. But I should definitely not take damage despite successfully blocking the spell.

PS: ingame the Damage Recap stated that I took about 180 physical damage by Camille's E, it's not an AA reset with her Q. Just in case that's not clear from the Video.
