我的AP真的被deny..小白兔,pjang老师请帮忙

刚刚我问了我的律师,结果居然发现移民局4/11就送文件给他了,他居然没有跟我说,天杀的,移民局说因为他们同时approve我的俩各AP(不同的i-485),当初律师也没有提到不可以送两各AP,应该说我们也很自然就申请了,线再因为俩各同时一起approve,後来移民局发现不可以降,就deny我的申请,下面是他们的文件
On Oct 4, 2007, you files an applicatin for travel document, case xx2 on behalf of yourself which was approved by USCIS on Feb 2, 2008. Hoever, it has now come to the attention of USCIS that the approval of your i-131, application for travle document was not clearly correct for the following reason.

According to service records, you previously filed an i-131, application for travel docuemnt, case xx1, which was also approved feb 2, 2008. there is no provision for an applicatino to be in possession of two approved travel documents.

Therefore, USCIS moves to reopen the approval of the second i131, application for travel document receipted Oct. 4, 2007. This application will be denied beased opon the above information.

我不太懂下面的意思
you are hereby afforded thirty days from the date of this letter to return to this office the second travel document approved for the application for travel document, xx2 filed oct 4, 2007.

我猜他的意思是以为我收到两各AP,所以要我退还後面的那个,不过我根本都没有收到,结果现在我赅怎麽办,律师跟我说要申请费580还有service fee 500.
问题是我也不知道我再送一各申请会不会又被拒了,所以请大家帮忙我看一下,谢谢
