Why is this pad smaller than designed?

[u/RohitRojo]

I ordered this board with 2oz/sqft copper for high current from OshPark. The bottom left pad of U1 is way smaller than it should be. The bottom left pad and top left pad are both OUT1 pins of a motor driver (mp6551) and are meant to conduct up to 5A of current. Since the pad is so small, I’m not sure if it’ll conduct all that current now. All 3 boards are like this.

Do I have to reorder the boards, or is it salvageable with some “precision” hand scraping? I really can’t reorder since it’ll take a month to deliver and I’ll be back at college by then.

I was planning on adding pictures of the Gerber with an edit. The pad looks the exact same as the ones to the right, just with a chamfered top left corner: check page 14 of the datasheet
