My first problem with SWX 2018!

I created a simple part. Created a new coordinate system. Saved the part as a step file using the new coordinate system.

When I opened the step file Import Diagnostics ran as expected but even though I have "Prompt for feature recognition as part opens" in my Featureworks options

Featureworks doesn't start as the part opens.

Featureworks is active

But it is grayed out under Insert , Featureworks.

Any ideas?
