Tree brush making very tiny trees

So I made a very simple low-poly tree in Blender and exported to Unity using fbx. When I simply drag the tree on to the game, the tree is the proper size but when I use the place trees tool in terrain editor, the trees that are placed are so tiny that I can barely see them. I tried Increasing the scale factor to a ridiculously large amount but it's still too small and creates a very weird shadow around it. Anyone know how to make these trees to come out to be the proper size? Here is an image showing whats going on: https://imgur.com/3YH9M4r The little dots you see are the trees created using the brush tool.
