Cars - BMW M4'14 - missing cockpit and roof elements while going race mode

Recently, just figured out a strange BUG seems to be occuring in COCKPIT view with the BMW M4’14 every track IN RACING MODE ONLY! The inner sides of the roof, windshield and installed cage elements are completely missing out of the car. Other tracks’ve just well running with the car. Dunno that’s happenning with other car(s) as well?!
