No morph target after importation in 4.17 and 4.16

Hello,

I am trying to import a mesh with morph targets from 3Ds max 2017 to UE4. After a few failures I made a simple test box in max with two to three morphers and skinned to a a simple chain of bones.
It’s imported in UE4 with no blend shapes at all. I made a blank project using 4.17 (the version of my project) and a 4.16
I made sure to check the import morph target in the import window as I made sure to check the “morph” under the Deformation pannel on the FBX export. I also tried the reimport trick I saw in a few post on the anwser hub

All that and still nothing, I’m running out of ideas and don’t know what I’m missing.
Did someone had the same issue and found what’s wrong ?

Thank for the help
