Last bug add to cart button in category view

[Awerso]

I still have a last bug with the add tot cart button in the category view.
I use the version with amount selector and the last problem is:
When you click on the button to add an extra amount of the product, instead of adding only one product, it adds two at a time (if you have 1 and click on the add button, the counter goes directly to 3 instead of 2 and then 5, 7, etc.)

The bug is that the steps are with 2 and not with 1. I tried to edit the default value etc. but also then he makes steps of 2.

The same problem for me. Any solution, please?
Thanks.
