FBX 3ds Max on Unreal Reimport, uncombined meshes become entire mesh

Hi Everyone
Newbie to Unreal moving from Unity.

I am working with Unreal 4.14 and Max 2016

When I do re imports / re exports with Unreal I am getting a nasty issue happening a lot.

I export to Unreal using FBX out of Max, Everything is brought in with combine mesh unchecked so the models with in the FBX are separate.
When I export the FBX out of Max again, all the same settings, on re import it combines the models so that every sub mesh becomes the entire model ruining my scene.

Attached 2 screen shots to show the issue happening

That is unfortunately a know issue in 4.14 and was fixed in 4.15
