Narrative:
Small aircraft X was a VFR arrival landing runway 36R at tampa international. His ARTS data tag went into the tower preview list after he landed. Small aircraft Y was an IFR departure off of runway 9 at tampa international. When small aircraft Y came airborne, his ARTS data block was an (F) tag showing small aircraft X. While this target had an small aircraft X tag on it, this tag also stayed in the tower previous list. The radar departure controller thought this departure was a missed approach because the (F) tag was tampa final radar. The aircraft involved had different beacon codes and it took all of us a little while to figure out what happened, and had it not been straightened out, it could have been dangerous.

Title: AN INACTIVE DATA TAG FROM A PREVIOUS LNDG ACFT INADVERTENTLY TAGS UP WITH AN IFR DEPARTING ACFT JUST AIRBORNE THEREBY CONFUSING THE CTLR.
Narrative: SMA X WAS A VFR ARR LNDG RWY 36R AT TAMPA INTL. HIS ARTS DATA TAG WENT INTO THE TWR PREVIEW LIST AFTER HE LANDED. SMA Y WAS AN IFR DEP OFF OF RWY 9 AT TAMPA INTL. WHEN SMA Y CAME AIRBORNE, HIS ARTS DATA BLOCK WAS AN (F) TAG SHOWING SMA X. WHILE THIS TARGET HAD AN SMA X TAG ON IT, THIS TAG ALSO STAYED IN THE TWR PREVIOUS LIST. THE RADAR DEP CTLR THOUGHT THIS DEP WAS A MISSED APCH BECAUSE THE (F) TAG WAS TAMPA FINAL RADAR. THE ACFT INVOLVED HAD DIFFERENT BEACON CODES AND IT TOOK ALL OF US A LITTLE WHILE TO FIGURE OUT WHAT HAPPENED, AND HAD IT NOT BEEN STRAIGHTENED OUT, IT COULD HAVE BEEN DANGEROUS.
