We are in the midst of filing our I751 removal of conditional status for my wife and daughter (K1/K2). The name on my daughter's green card has 1 extra letter in the name. We don't have much time left to file the I751, so we'd like to know the best course of action to handle this. We checked all our applications and her name is correctly spelled throughout. Also, her passport and all other paperwork are spelled correctly. As far as we can tell the Green card and notice of action (NOA) are the only places where it's misspelled.
Any advice would be appreciated. I kind of think that if I file the paperwork (spelling everything correctly), they might not even notice that it's misspelled on her card, because it's a hard place to notice. Then we could claim that we never actually noticed it if they bring it up.

But, perhaps this isn't the WISEST course of action. Advice please!!! Thanks and Happy New Year to All!
