Unreal 4.20 re-applying materials on LOD import

Hey,

everytime I re-import some LODS for a static mesh, the base static mesh materials are duplicated in some strange manner.

For example after 5 re-imports of 2 lods - 0,1. I have around 500 materials on my static mesh. And I cannot delete the material slots but can replace them with the correct material. But doing this 500 times would take a while

Simple fix is to reimport static mesh and LODS. and apply the material, but everytime I press ‘reimport’ or wish to update my lods further I will run into the same issue

Just thought you guys should be aware of this bug.
