BlendShapes not Showing Up (Blender -> FBX -> Unity 2018.1)

I made a mesh in blender with several shape keys and no animations and I exported it to an FBX file for use in Unity. When I was using Unity 2017, it would import with a Skinned Mesh Renderer with Blendshapes (I made sure Import Blendshapes was selected) but in Unity 2018.1 it imports with a normal Mesh Renderer and no Blendshape section appears. Even if I add a Skinned Mesh Renderer to replace the original Mesh Renderer, no blendshapes appear. Is there a way to import multiple Blendshapes from Blender to Unity with Unity 2018.1? I am not using any armature and the mesh has no animations. Thank You! Blender: How it Looks in Unity:
