My Menue to the left is damaged. Why? What did I wrong?

Dear gassnergrafik,
Thanks for contacting us and choosing our product!
About your problem I checked your site. In this case almost is css of our module or template over on each other.
You can fix it by style css (add this code at custom css option):
#leftColumn ul.menu{
background: none;
}
Hope this help!

Thank You, Yes, this is the solution!
regards
Norbert
