Same here.

I don't see such button nowhere.

> 4. Click on the arrow near the project to expand the project

Which button, which project? I'm lost at this point.

Is this a regression in 4.14?

The issue here is not in the StructuredViewer, but in the ViewerFilter implementation that returns unknown elements.

Looking at the Capella code [1], my first guess would be that it has a stale cache.

Moving to Sirius for further investigation.
