Faceted module shows blank page for some results

[Juan Rios1]

Hello! Hope all is well!

I am using prestashop 1.7 and the module is version 3.7.1

Some filters work while others do not, the page just turn blank pretty much.  Please see for yourself: https://riograndeboots.com.mx/12-vaquera

When you enter that link, you will see this:

 

The filters in red are the ones that don't work, while the other ones work perfectly. This is the same for a lot of my category pages.

Does anyone know why this happens?

Any ideas are welcomed!

Thanks
