Edit this page and switch the post content editor to the “Text” tab. Now remove any HTML tag from in and around the shortcode, specifically the
pre tag. When you copy paste shortcodes and there options from a web page always switch to the Text tab first otherwise the underlying HTML from the page the copy was from will also be pasted. This is not a Connections issue or bug, it is how the WordPress text editor works.
Here’s a link with a tip on working with shortcodes that I hope will be helpful.
Hope that helps, please let me know!
