Zone stamps are the only objects that will adjust as you alter a zone.
Standard objects can get information from a zone but as you have discovered you must force the object to run its scripts for the zone info to update.
This can be done by opening and closing the object settings, or a simple screen zoom or pan should do it or a 're-build and regenerate' command (CTRL+ALT+SHIFT+R).
Note: 're-build' command (CTRL+SHIFT+R) will not work as this does not regenerate the model.
