Horizontal Filter Issues

hello,

I just recently purchased the premium version of the Yith WooCommerce Ajax Product Filter and decided that I would like to use the horizontal filter on my pages. The link above is to one of my testing pages for the filter. My issue is that the filter is too large, the text “Show More” in the drop-down won’t change colors, and the drop-down doesn’t have a scroll like it does when opened in the sidebar filter, so the drop-down goes below my footer.

As far as I am concered no CSS has been able to affect how the filter looks in size or color. The setting have been changed to make the text black but still the text shows up as white and there are no settings to change how the drop-down looks or functions

The page I need help with: [log in to see the link]
