Icons showing in widgets as well as posts

Hi,
Firstly, thanks so much for the plugin. This is exactly what I was looking for. It is nicely designed and very flexible.

However, I am seeing a strange issue. The social sharing icons are also showing up in some, but not all, of the widgets on the website I am testing the plugin on. They are text widgets that have shortcodes that enable different functionality, like contact forms and post listings, but I don’t understand the inconsistency of why they appear on some widgets and not others. I suspect it may be this “Dynamic Widgets” plugin I have that controls which widgets appear on which posts / pages.

I do not want it to show on widgets at all, and I have the option “Shortcodes In Widgets – Allow shortcodes in Text widgets” unchecked.

Do you have any ideas off the top of your head why it is doing this?

Here is an example of a page where it is occurring – note the multiple sets of icons appearing on most of those widgets, which are text widgets and use a shortcode, and are dynamically set to only appear on industry-related posts:

Any help would be greatly appreciated. Thanks for your time.
