Why the effect is applied, even though it's set to zero at a certain point

Why the directional blur effect is already blurring my image even though it's set to zero at the position of the playhead and didn't reach the keyframes yet?

I see you have time remapping applied.

Nest the clip and apply time remapping inside the nested sequence. 

Then apply the directional blur to the nest in the main sequence.

Thanks, I'll try, but why is it happening?

I don't know why you need to nest. I just know that if you try to apply time remapping along with another effect in the same sequence, there will be issues.
