Icon List custom colours not working when using more than one instance of a list

Hi

I recently updated to from Enfold 4.5.2 to Enfold 4.5.5, after doing so the Icon List content element only displays the correct custom colours for the first instance on a page, all subsequent icon lists on the page revert to the default colours.

On inspecting the element it looks as though the style element is not being rendered correctly, inspector (in Chrome) displays:
<div style=” style=” background-color:#0668b3;=”” color:#ffffff;=”” ‘background-color:#0668b3;=”” ‘=”” class=”iconlist_icon avia-font-entypo-fontello”>

Note the beginning style=” style=” which seems to break the style and following classes.

I have cleared browser cache, cleared site cache (WP Super Cache) and deleted old JS/CSS via the Enfold settings, and the bug persists. This happens on existing and new pages, the bug is also present on both our environments, Development and Live (if only I had of spotted it on Dev before I did the update on Live). The theme update was done by deactivating the theme, deleting and then uploading the new theme package downloaded from Envato Market, activating and then reactivating the child theme.

URLs of where this can be seen below:
