Layered Navigation block breaks "show all" on Category Page

[ZLau92]

SITE: http://retail.roxtarmusic.com/

PrestaShop version: 1.6.0.9

Theme (default/customized): Customized "Minimal"

Code (original/modified): Mostly original

Hosting: On a machine on the floor running Debian

PHP version: PHP Version 5.4.4-14+deb7u14

Browser(s) concerned: All

So, I want to start by saying that prestashop is absolutely the very most useful piece of php web software I've ever used. I am having a problem with the Layered Navigation block though. Once I enable a filter in the Layered Navigation block, the show all button stops working. Also, once the filter is enabled, the page numbering (ie Prev,1, 2, 3, Next) shows up only above the product list, and the one below disappears. If I go to a category page, and refrain from using the layered nav block, everything works just fine.

 

 

A specific example would be this page: http://retail.roxtarmusic.com/30-snare-drums#/manufacturer-gretsch

When I click the "show all", nothing happens

 

 

Any help would be much appreciated. This is the first issue I've come across that a quick search through the forum couldn't remedy.

 

Thanks,

 

Zach
