Animations_Fade In/Out not working

[JRR_render]

Keyshot 7.2 Pro, Windows 10, Modeled and animated in SolidWorks 2017, Export as fbx file (for model and animation keys) using Simlab plug-in.  Import FBX file into Keyshot.

I tried applying fades to some parts in my model and the feature is not working.  The parts just appear with no gradual fade in or out.  In the included animation, the wing panel is supposed to fade in as well as the figures, but instead they just appear instantly.  I do have motion ease set to ease in or out depending on what I'm trying.  Any ideas why the motion ease feature is being buggy?

I think it would be too hard to diagnose without looking at your KeyShot file...

Will - how can I share the file with you for you to take a look?

I don't think I saw that. Did you email will@luxion.com?
