Not sure if this is the correct way to report a bug in the Coherence theme, but here goes:
When an iconbox shortcode, is laid out in the Columns shortcode, and placed inside a Slider content Shortcode, an additional "<p> </p>" is generated that affects the layout of the iconbox.
Trouble shooting to date:
1. Please see the page above. i have laid out the shortcode to display the error. A quick look will confirm this bug.
2. I have been able to replicate this bug on my local install, with no plugins installed.
