Resetting Grid Control Metrics

Does anyone know how to reset the metrics to their defaults for a database in Grid Control? During my testing, I have apparently changed one of the metrics on a database to an invalid format. Why Oracle would allow me to save it that way is beyond me, but that is another story. Now, whenever I go to that database, select metrics and policies, and choose ok (not changing anything), I get the following error: "Threshold Values - The format of the threshold values is not correct." However, it doesn't tell me which one of the dozens of metrics is invalid. It also does not include a reset all option. At this point, I just want to reset all the metrics to their default value and continue testing. Any ideas?
