Hello,

When you create a button and setup a link the hover parameter you define in the panel setting are overridden by the default one.

Here is the cause of the problem : 

.awe-btn:hover, a.awe-btn:hover {    text-decoration: none;    background: #0E83FF;    background: -webkit-gradient(linear, left top, left bottom, from(#258efd), to(#066bd7));    background: -moz-linear-gradient(top, #258efd, #0E83FF);filter:progid:DXImageTransform.Microsoft.gradient(startColorstr='#258efd',>;}

The background gradient override that rule :

.awe-btn.awe-section-22-0-1-3-button:hover {color: #2789D7;background-color: #FFF;}

Regards,

Alex

Edit : The bug appears only when I'm on the frontend, it works on the backoffice.
