Hi,
You're using HikaShop with the "bootstrap design" but your template is not "bootstrap 2", it is "bootstrap 3" and it also override some HikaShop views in order to have a "bootstrap 3" design.
Because your template does not override HikaMarket views and does not support the "bootstrap 2" CSS classes, the vendor listing made by HikaMarket is not display as it should.
So, you can see to deactivate the bootstrap design in HikaShop or you can override some HikaMarket views (vendormarket | listing) to use bootstrap 3 CSS classes instead of bootstrap 2 one.
