I do not know if you have figured it out yet, there is a solution I have discovered that did work for me. If you are using the ProceduralSpawner to place the trees on the landscape I can be of help here. First select the ProceduralSpawner you want to use, and under the Details tab select the Foliage Spawner and open it up. Once you have it open, you should see a listing of the Foliage Types and other items are want to use, so open one of the Foliage Types to open it up. Once it is open, click the down arrow at the bottom of the Placement section to open the listing of Inclusion and Exclusion Landscape Layers. What I had found here is to either create or simply remove the Inclusion Landscape Layers Array Elements and it then placed the Foliage to the landscape.
