Light build issues with my speedtree grass

After I build my light for the speedtree grass and trees I get an error saying my uv maps are overlapping. I have checked my lightmap information on both the speedtree and ue4 side and the information matches. Does anyone have a trick?

I made no changes to the tree before importing it into the scene. This is the error I receive when the light is built, how do I fix the uv’s from within ue4? I have always fixed them before I brought an object in.

You might have to make some changes. On a couple of models I noticed normal maps not enabled causing weird lighting etc.
