Continuity mistake: At the harbour, Florence's ponytail is suddenly windblown in the shot when Jack says "I'd say that gives you a pretty good reason to want revenge." (00:37:15)
Continuity mistake: Officer J.P. Hooper holds the wad of bills for an unnaturally long amount of time, but if it was for sake of continuity, too bad; he holds it with his arm at a different angle between shots (he did not have his elbow on the desk, and all of a sudden he does). (00:37:20)
Continuity mistake: The detectives reach Cressida Friend on the beach. Jack waves around the letters with his right hand; his left hand is in his pocket in the front views, but it's on the waist in the wider shot. (00:32:00)
Continuity mistake: JP presents the key after his visit to Dread Locks; Tobi Bakare is holding the plastic bag in a different way throughout the scene (just one finger in the reverse shots) and at towards the end he lowers his hand in a shot but it's again up in the next. (00:27:10)
Continuity mistake: When Jack speaks to Florence about his ambiguous intention to spend some quality time with the Commissioner, he changes position in between shots, with his excited fist raised while his left hand disappears from sight. (00:15:10)
Continuity mistake: After the intro, Florence reaches Jack at the shack and leans against the wall while he's whining about the speech he has to write about their boss. In all close-ups Joséphine Jobert's hair flows in front of her shoulder, but in the one wider angle (when she shrugs him off with "I don't know, sir") her hair is fully behind her back. (00:04:25)
Answer: There's probably no particular reason. Sets and props on long-running TV shows often change as needed and for various reasons throughout a series run.
