inverted bumpmap with custom UV's

I'm getting some strange results with bumpmaps when importing my models with cutom UV's. The bumpmaps work fine when scaling the UV's within Lumion. However, when using a scale of 0 (custom UV) the bumpmaps seems to take on a negative value. I have attached some images for reference. This also happens when using Lumion's preset materials. I'm using the Updated Demo.

I can't post the Lumion file because I'm trying out the Demo Update. I have posted the collada file which is just a simple UV mapped box. Same problem occurs with all my models regardless of the imported format.
