When a mesh in Blender is Duplicated and exported as an FBX, then imported into Unreal with Combine Meshes unchecked, then both meshes reimported, one of the meshes has another mesh added to it. The mesh looks as though it has been imported with the option Combine meshes enabled.

Steps to Reproduce
  1. Download attached FBX
  2. Import into an empty project
  3. Uncheck Combine Meshes option under Mesh in the import settings
  4. Cubes will them import as 2 different meshes (CubeTest_Cube and CubeTest_Cube_001)
  5. Right click < Reimport both of them
  6. See CubeText_Cube_001. There are now 2 meshes

Expected: No other meshes are imported or combined. There is still only one cube

Results: Another mesh is imported and they are combined. There are now 2 cubes
