[GAMEPLAY] nocturne Shroud of Darkness block more than 1 spell

Hello,

I saw this bug on my last game I played as Malzahar, the Nocturne could block my E and R everytimes I did it E>R quickly to remove the spell block. It's not an order mistake because Nocturne never had the E on him and the R void zone never came under him but both spell were on cooldown.
