請教863211老師, about EAD card

Just checked online about my EAD renewal status: card production ordered four days ago, but I also just found there is a letter wrong in my name on the receipt. It is a 'c' instead of 'o'. My name printed on application form is right. I don't know what letter they are going to print on the card since I didn't received it yet.

Do I need to do something now?

What should I do if they do put a wrong letter for my name on the card?

Can I start to work before they correct the wrong letter mistake?

 

Many thanks.
