LumenRT CE Update 2 - Problem with Add Plants - Saved Preset Selections

I can save a selection of trees to a preset, but when ever I try to pick and use the preset LumenRT either becomes unresponsive or crashes.

In the cases when it becomes unresponsive it will chime each time I click the mouse within the application window, but it is otherwise locked and unresponsive.
