Glitch or Bug in Defence

Hi EA Team,

While playing your FC mobile game, I've noticed a recurring bug that occurs during Head to Head matches. Specifically, when the opponent attempts to dribble down at the wing, the defenders seem to vacate their positions, leaving a significant gap. Consequently, I'm forced to sprint to cover the center-back position, which is left unattended. I've attached a video for reference, and this issue has occurred multiple times, suggesting a potential glitch or programming error.
