To Pjiang, Xiaobatu and others DAXIA

I found several mistakes in my 485 cover letter. I have 3 packages respectively for myself, my wife and my kid. I found the exhibit list for my daughter in the cover letter was wrong ( it doesn't match the exhibits in the package). Do I need to send them a letter to correct it? I mailed out my 140 and 485 together and have not gotten any response. The checks are not cashed either.

Thanks for your help.
