Module class suffix app-box

In Jomsocial, I'm trying to put a box around the HelloMe module. I add a module class suffix of (space)app-box.

The box appears but app-box appears twice in the code, drawing 2 boxes.

<div class="cLayout">
<div class="cSidebar">
<div class="moduletable app-box">
<div id="cModule-HelloMe" class="cMods cMods-HelloMe app-box">

I would like a single box like the Search module below it and get rid of the box with the red arrow.

Hi

Jomsocial module positions are a little bit different. Please come up with a new module class suffix, for example " app-border" and show me the page where I'll be able to see this module so I'll tell You the code.
