Weird LayerSlider WP bug?

I am using LayerSlider with the Enfold theme for http://www.kariosgames.com and I have a strange bug. I make a slide with a few layers and it works great. I make a second similar slide and I am getting errors that prevent the whole thing from loading. The errors look like this:

Failed to load resource : http://www.kariosgames.comhttp//www.kariosgames.com/wp-content/uploads/2014/01/appStore.png

In the respective layer, the image is stored as:
/wp-content/uploads/2014/01/appStore.png
but it seems like at some point the relative filename tries to become absolute unsuccessfully resulting to the error above.
The first layer works if I hide the second one. Any ideas?
