    Note The Tracking > Email Overlay View for emails that use A/B Test content blocks show only one of the content blocks, regardless of whether you select the job details for block A or block B. The tracking results are unique to the job but the email preview doesn’t show A & B respectively, but only displays a single default block for each job. A/B testing of separate emails that don’t use A/B Test content block show the unique email for the job whose tracking you select to view.
