As Gabriella speaks to Brink before the first downhill race, there's a closeup where her helmet is buckled, but in the next shot she's taken it off and it's unbuckled, but in the next shot when she tucks down, her helmet is buckled again.
At sunset, Gabriella, Peter and Jordy decide to disobey Andy's directive to train and instead go scouting at the invitational. When they arrive at the invitational, the lighting and position of the sun indicate it's closer to noon.
