Attaching/linking a citation to a marriage event.
A marriage event to link the two individuals was created PRIOR to attaching/linking the citation.
The original form recognized the event, overwrote it and linked the citation to both individual.
The beta form did NOT recognize the event, it created a new marriage event and then created phantom profiles for both individuals. These phantoms are visible on the profile page of both individuals only. The only way to get rid of the phantom, is to delete the profile altogether, and redo.
This presents no problem is there are no linked citations to the profiles and the profiles are linked to no other profiles, and if you recognize that 2 same profiles are not duplicates, but an original and a phantom. If any of the above are not true, then, yes, it is an major issue.
