Fortnite (L3 key spins)?

I have a small problem

When I'm in Fortnite (PS4) with L2 targets, the crosshair goes up automatically and when building too. So it can't be the controller because it is new and until now I only have this problem in Fortnite. Thought if I put my Deadzone up it worked, it had it too, but only once in a while. Knows what you can do, I would be very happy about an answer.

This is due to your Fortnite settings.

Reset everything and reset everything

I already had, thanks anyway
