Fortnite mouse wheel reset bug?

For a few days I have had a problem with resetting the mouse wheel in Fortnite. It just doesn't work on my first account. I have already reset the settings and reset everything, but it still doesn't work.

Everything works normally on my second account, so I asked myself why this could be.

I thank you in advance for your answers.

Oh, that's not only with Scrollwheel reset, but actually with every bind. You just have to pull through until it is fixed.
