Layered navigation showing 0 products and no price slider

[snowmania]

Ive installed the layered navigation block, enabled all categories and most filters (Set "Hide filter values with no product is matching" to no) clicked on the build and rebuilds but nothing shows up apart from the filters with 0 values although it does display what would be valid for that category.

 

The second thing is the price slider wont show, ive seen other posts from people saying no sliders show but at least the weight slider shows for me but the price doesnt.

 

Ive attached an screenshot although I don't know if that will be any help

 

Only had prestashop a few weeks so on up to date versions

Prestashop 1.5.3.1

Layered Navigation Block 1.8.9

 

Ive tried a few different combinations of things but nothing seems to help.

 

Any suggestions would be a great help
