Astro C40 Fortnite R1 bug?

Since the last Fortnite update, the Astro C40 has skipped a weapon slot for me after clicking R1 once, sometimes even 2. What could be the problem?

You don't really have to worry about that. It's been the same with my mouse for months.

So, don't think about it anymore and still try to get an epic.

I have the Same Problem still now with My astro c 40
