Is there a button combination that toggles auto sprint?

Pretty often mid game my players just don't stop sprinting as if i'm holding down R2/RT non stop.
I always have to forfeit the game when this happens because it's unplayable and i have no idea why this even is a thing, it's so dumb. Restarting the game fixes it but it's still really annoying.

Is it a bug or a really bad feature? and if it's not a bug i would like to know how to toggle it off thx.
