Widget styling

Hi,

I’m trying to use your table of content plugin in the widget section of my website. I’m using the theme Theme X Pro.

The problem is that it seems that the style I set in the settings of the widget does not seem to reflect on the real live page in the widget area. It does show in the actual content of the blog post but not the widget area.

Please see attached image where you can see an example of the styled table of contents in the content and a non-styled table of contents in the widget area.

How can I get this styling in the widget area as well?

Thanks.
