Looking into this video:

We can see the FLAPS CONFIG IS CLEARLY 15º for the entire TO procedure, the AC does all correctly and arrives into destiny airport (Minsk) in perfect shape.
Gear is retracted about 6 secs after being airborne and 15º flaps are retracted to 0º about 115 secs later.
Whatever the reason for the flap retraction was -- wouldn't it be much too early in the flight for them to be retracted? It seems more typical like in your video that it happens after 120 seconds of flight.
