Problem:
The user is using Kadence Info Box with Toolset dynamic source. The generated page is not correct.

Solution:
It seems that the issue appears when the entire box is configured to be a link. Check this screenshot http://prntscr.com/13146yl
Once we configure the link to be only on the "Only Learn More text", the issue disappears. Check the result http://kadence.nevetssoftware.com/play/

According to the HTML specification, we can't have a link inside a link. Check this online thread https://stackoverflow.com/a/9883044
