Ruby Shopify Theme

Hi guys.
Recently I have bought a Ruby Shopify theme. I have some challenges in customization. For example, my buttons looks like grey bars at some pages ( in the slider section) , and my compare to price ( sale items) are showing a weird price ( in the sale carousel product section).
I will upload a screen shoots so it will be more clearly.
Thank you for helping me out.
