3DS Max Morpher flickering when imported to Unity

I’m doing some tests in 3DS Max with a morpher animation. I’ve done this before with simpler animations and I don’t recall having any issues, the thing I’m trying now has about 100 morph targets, though it’s just a cylinder extending along a spline.

It seems to export to fbx ok, and it plays back smoothly inside 3DS Max. As soon as I import it to Unity though, there is some annoying flickering. Moving along the timeline it seems like it’s going back and forth frame-by-frame. Any idea as to why this is happening?

Here are both the .fbx and the .max file for anyone willing to have a look:

To make things even more strange, I sent the .fbx to a friend of mine and he told me that on his machine the animation plays smoothly. During this time I’ve transitioned from Windows 7 to Windows 10, 3DS Max 2014 to 3DS Max 2017 and from some previous version of Unity to the latest. And the flickering keeps on occurring on my PC. Go figure.

The only thing I can think of, is that I’m working on a 64-bit version of Unity, while my friend is working on a 32-bit version.

Can anyone else give it a try and tell me if it works well for him and tell me if he’s working on a 32-bit or a 64-bit version of Unity?

For the record,. here’s the hiccup I’m experiencing:
