Price filter using blocklayered module not working on mobile sites

[hbee]

Hi, I hope this is the right place to post this question.

I have a problem on the site www.zocas.es. When viewing the site on a desktop computer the price slider for the filter works just fine, but on mobile (and tablet) versions, it doesn't. It shows correctly but is static: cannot move the slider. Does anyone know what could possibly be causing this, what the solution might be? We are using  logancee theme  with prestashop 1.6.1.24.

Any help is greatly appreciated! Thank you.
