Narrative:

There was OJT being conducted at the sector; which was combined (46/47); and I was the on the job training instructor (ojti). The aircraft in question; aircraft X; was handed off to rsw approach and the data block was approximately 2 miles within the lateral confines of their airspace. Aircraft X was on course direct [to] landing [airport] level VFR at 3;500. Both the trainee and myself got distracted with IFR traffic within the R46 side of the airspace and did not recognize that the data block for aircraft X dropped off of the scope; which the d-side admitted to doing.rsw approach proceeded to call the sector and request communications on the aircraft. The d-side advised the r-side to transfer communications on the VFR aircraft within rsw approach's airspace. The r-side trainee brought up the data block and switched the aircraft. The pilot said he had traffic that 'passed pretty close' at the same altitude. Upon closer review; the r-side trainee identified a VFR target indicating 3;500 approximately 1 mile behind aircraft X. After calling the traffic; she successfully shipped the aircraft.

Title: Miami Center Controllers reported of an unsafe situation where the assist Controller dropped a data tag on an aircraft that had not had communications transferred to the new sector.
