That was a little strange indeed. Are the property type of review checkbox? Or are you setting them manually somehow?
In either case, glad you worked it out, and after I wrote my answer I remembered that I did a larger post related to how you also could use tags to accomplish the same. See thread below:
Using tags one envision doing:
choice(rewiewed = "true", "#_/OK Reviewed", "#_/NotOk Not Reviewed") as Reviewed
It’s matter of preferences, but I just wanted to mention this tag trick, as it can be very useful in some occasiations.
