Am I doing Import All Wrong for multiple .fbxs?

Since I’ve started using UE4 (4.12 to 4.14) I haven’t been able to get the Import All function in the FBX Import Options to work.

I’m not sure if it’s something I’m doing wrong or not so I thought I should ask as it’s really slowing down my asset development.

Currently I export each individual mesh for import into UE4 from 3dsmax. Then I select all the exported meshes and drop them into the content browser and try to select import all, but it only imports 1 mesh at a time displaying the fbx import options every time. This also occurs when importing asset packages that contain meshes as well, I have to click import or import all for each individual mesh, which needless to say wastes a lot of time.

The only thing that I can think of trying is a complete uninstall of all epic games launcher / UE4 and reinstallation, but I’d like to avoid that if possible if I’m just doing something silly like not ticking a setting in the editor somewhere that makes import all work.

I appreciate any help or suggestions you can give.
