Red Light Bulb - Progression Step - Possible Result of A/B Test?

Hi!  Has anyone ever experienced a Red Light Bulb after running an A/B Test - where the subject lines were completely different? I've run many A/B Tests but this is the first time I've ever encountered this.  Thus, b/c of this the results of the send were not reporting in any of the progression steps nor syncing into the Campaign in Salesforce?  *I was able to run a report through Database and upload into the SF Campaign that way; but curious if anyone else has experienced this and how you were able to resolve through Marketo directly if at all?
