Buzzer Beater Achievement

[Anakaris7]

I don't know what I'm doing wrong I put the time on 2 minute halfs and its on All-Conference Difficulty and doing it on play now and I held the ball the whole time till it got down to like 2 to 4 seconds and I shot a 3 and won but the achievement didn't pop up is this achievement glitched or what? someone please help
