strange line

HI all

I have a strange line showing in the bottom position ...you can see it in the screenshot. This is a slider Module.

When I place the Module in the adv_bottom issue is the same.

Placing the Module in banner1...ALL SHOWS just fine.

When I create a empty own module and place it in the bottom position shows without a line.

I have tested a few Image sliders in that position....and all show this strange line.

Hope someone can help
