Hi @GeorgiaHards27 Welcome to the Candy Crush Friends Community.
Lives never got boosted to 5 for finishing a level to my knowledge. It may have been showing back at 5 for you if you did not lose a life while playing the level? It will only increase to 5 as time passes after losing a life, receiving from friends or purchasing more. For more info on sending/receiving lives check this
