Shortcode Doesn't Work Inside Custom HTML

Hi,
First I have to tell you that you’ve done an awsome job with this plugin. It’s simple, it’s flexible, and it works.

I have one issue, and it’s kind of weird. I added my own custom HTML via the Advanced Options and I’m using a shortcode from the Social Count Plus Plugin inside. For some strange reason, the shortcode only works inside of the content area of the page (using SiteOrigin’s Pagebuilder plugin – which uses widgets), but not in the sidebar widget.

I am able to use the Social Count Plus shortcodes in the sidebar in an enhanced text widget on it’s own.

Do you have any ideas on how I can get this working on my sidebar? It works great on a page.
