JA Property Welcome module, extra line

Hi this line appears on welcome module, please see what's possibly wrong with it?

It's border of topbar on left side, if you want to remove it, pls use this custom css:

.t3-topbar .topbar-left { display: none !important; }

put into the file: /templates/ja_property/css/custom.css (Create this file if it doesn't exist)

Regards
