Rule test is working in my tenant. If this is still an issue, please submit a case. If the retrohunts are generating alerts, that would be due to the rule being set to alerting. You could temporarily disable alerting from the rule and run a retrohunt to generate detections only, or you could copy the rule and run it with alerting turned off instead.

Unfortunately, I can't submit a case due to not having Standard Support but I will try disabling alerting and do a retrohunts as a workaround until this issue is fixed.
Thank you @cmorris .
