Node 'preview' and watch values unequal

I’m trying to check if elements are in spaces using the Space.IsPointInsideSpace node in the Rhythm package, but i’m getting some weird behavior where the node appears to execute correctly (pin/drop down output looks correctly), but the data isn’t passed, and an attached Watch node returns a null value.

Not really sure how to troubleshoot this …

Restart Revit and Dynamo. If that doesn’t fix it please provide a sample RVT and your DYN.
