Widget filter terms are not updated with proper style on Riode theme

I’m using Riode theme. I’m having widget taxonomy filter – color and size.
Color is displaying fine but when a given color is chosen all the the styles of all color divs are gone.
This is how HTML looks before selecting any color:
<span class=”vi-wpvs-option vi-wpvs-option-color” data-option_color=”rgba(214, 59, 29, 1)” style=”background: rgb(214, 59, 29) none repeat scroll 0% 0%;”></span>

and after the page is updated:
<span class=”vi-wpvs-option vi-wpvs-option-color” data-option_color=”rgba(214, 59, 29, 1)”></span>
The style is not created based on the data-option_color attribute.

Similarly, buttons are not displaying style for active terms.
When the page is reloaded in the browser (F5) all the items are properly displayed.

There are no errors in the console. This is definitely theme related issue but maybe you can give me a hint why this is happening and suggest a solution.
Thanks in advance!
