Pit stop Bug (held in pits for nothing)

I was playing 2 player career mode in Bahrain. I came in for my first pit spot on a 50% race and once my tyres were changed I was held in the pits for over 15 seconds for nothing. There were no cars in the pit lane, and was held for no reason for a long time. The mechanics looks like they were holding a front wing however I had no wing damage. After 15 seconds of being held they let me go. 

awful bug as ruined my race and had to alt f4 the 50% race in
