Layered navigation block problem

[georget777]

Hello

 

There is an issue with layered navigation block on mobile phones and tablets.

 

When i use it to filter a category, it completely crashes.

 

It works the first time but you can't use it again.

 

It doesn't filter anymore and don't collapse as well.

 

I changed the theme to the default and get the same behavior.

 

Any ideas please?

 

thank you
