Narrative:

I issued a squawk to aircraft X; was distracted by some departures and conflict alerts to other helicopters is the area. Then noticed the [discrete squawk] code getting close to the tower's airspace. The problem is aircraft X was already tagged up on another non-discrete beacon 1200.I don't know exactly what happened. I was excited because of the helicopters; aircraft Y; aircraft X and two other 1200 codes all in very close proximity to each other and in conflict. I may have accidentally mistagged the 1200 code. But recently we started the fusion program at our facility and was wondering if the fusion tagged the wrong beacon. If this is the case then that would be a big problem.
