Looking at the flight on FR24, the initial approach involved quite a tight left turn to position on a short final position for RWY 23 at around 450’. Such an approach leaves little margin for ensuring the aircraft is setup properly for landing as there are many changing variables.
It is possible that the aircraft was not established in a stable configuration, or the landing checklist was incomplete, and so the aircrew elected to overshoot and re-circuit for a more normal approach.
It is also quite possible that ATC directed the overshoot for a number of reasons such as an aircraft ahead being slow to exit the runway etc.
Listening to the communications between the tower controller and the aircraft might give more insight.
