Selecting RINIS1A arrival via ABBOT for ILS 22 in EGGS produces a complete wrong distance after IDESI (6200 nm). Not sure if this is an Aerosoft bug or an Navigraph procedure error. Entering the waypoints and altitude constraints manually, the distance calculation in the A320 is correct.
My route for your reference:
