Hi Sam,
Thanks for using Shortcoder.
Shortcoder is unaware of the code i.e the shortcode content. The content is inserted into the page as is.
May be the shortcode content code didn’t work well with overall required syntax by the slider.
You can try replacing the “shortcode” with “shortcode content” at the same place and the same issue would occur.
You can also compare the working HTML and the HTML after shortcode is inserted.
Please do let me know once you have figured out the issue.
Thanks,
Aakash
