Aircraft X checked on with Sector 21; east of ZFP.  The route of flight was ZFP BR21V PBI. At some point over or west of ZFP; myself or the R-side dropped track (not RS'd (Removed Strip)) on Aircraft X.  The Intruder was noticed and a manual handoff call to the WALIK controller at PBI was made prior to Aircraft X entering PBI Approach airspace.  The aircraft was then tracked-up and track control transferred to PBI. Scan diligently for intruders and ensure track is being dropped on the correct aircraft.
ZMA ARTCC Controller reported an aircraft they thought was an intruder; but was actually an aircraft whose radar track was dropped by ATC.
