not entirely sure why, but its your theme...

first one coming from this css:

#logo {
    background: url("images/logo.png") no-repeat scroll 0 0 transparent;
    display: inline-block;
    float: left;
    margin: 0;
    outline: medium none;
    overflow: hidden;
    padding: 0;
    position: relative;
    transition: transform 1s ease 0s;
    width: 290px;
}

in style.css...

2nd one coming from this css:

h1 a {
    background: url("logo.png") no-repeat scroll 50% 20px transparent !important;
    display: block;
    height: 113px !important;
    overflow: hidden;
    padding-bottom: 0;
    text-indent: -9999px;
    width: 312px !important;
}

in theme file log.css

if I had to guess, I would say its lazy css intended for the wp login page...  its way too generic a css in log.css...  so because we have a login form in the form, the overly greedy css is incorrectly adding a second logo because of the poor css...

what can you do?  adjust the css in log.css so it only affects the wp login page... or you can remove the inline login form in the forum and instead put a link to the wp login page...
