Trouble submitting F2L alg to SpeedCubeDB.com

[Fred]

I'm trying to submit an F2L alg for case 5 in the front left slot, and I can't figure out how to do it. I'm trying to submit U2 F' L F L' U2 L' U' L, but it says it doesn't solve the case. And yet y U2 F' L F L' U2 L' U' L solves the front right case. Can someone help me figure out how to make this work? Thanks.
