I did not know such a plugin was around lukas seems to have the solution, was it difficult to put right or would you say you need to know coding, I am not that great with code

OK Hutch! Forget about my previous comment.
I found the solution for you.
You will have to edit your functions.php file and add this code:
"add_filter('widget_text', 'do_shortcode');"
without the quotation marks.
The reason you are getting this code visible on your website is not because there's something wrong with the plugin itself, or how you input the text in your editor.
It's because the WordPress is not parsing short codes in widgets by default ;)
When you add the provided code to your functions.php file you're basically enabling parsing for short codes in your widgets and those short codes are ran.
This is how to do it:
Go to your wp-admin dashboard, click on appearance, than editor. Find "Theme functions" tab on your right hand side, click on it. Add the code in "/***** Enable Shortcodes inside Widgets *****" section (just press ctrl+f - it will bring a small popup, type "widgets" in and it will find all text containing "widgets" in it on you site and highlight it, you can move from one part of the text to the other by clicking on an arrow in the popup), simply copy+paste the code in appropriate part of the file.

If you don't have this section in functions.php simply add this code to the file:

/***** Enable Shortcodes inside Widgets *****/

add_filter('widget_text', 'do_shortcode');

Make sure that the code goes before the last php tag (this is the tag: ?>) in the file.
Save the file, reload the page. If needed clear cache in your browser and check if it worked.
Check the image for reference - all steps are numbered on the image.
Hope it helps ;)

Hi Hutch!
Can you please provide a screenshot of your editor in wordpress? All I need to see is the peace of text where you put your CBC code in. Thanks ;)

I wish I could help you but I will be watching for future updates on what to do
