EAD/AP Double Submission

[slimbugz 0]

I posted my application for renewal of my EAD/AP (Form I-765  and Form I-131) combo card through USPS on 02/21/2017 and when I didn't receive any notification of acceptance of my application nor delivery of my mail to your office while USPS informed/insisted they delivered my mail. I became confused and resent another application for renewal of EAD/AP (Form I-765  and Form I-131) combo card through USPS registered mail on 04/07/2017 thinking I suffered a mail lost in transit in my first application.
 

On 04/11/2017, I received an email from Do_Not_Reply_Lockbox@dhs.gov starting that my application was accepted and routed to USCIS National Benefits Center for processing with receipt number Receipt Numbers MSC1791004689 and MSC1791004688 for both Form I-765  and Form I-131.
 

On 04/12/2017, I received in the mail Form 1-797C (Notice of Action) for both Forms I-765 and Form I-131.

 

On 04/18/2017, I received another email from Do_Not_Reply_Lockbox@dhs.gov starting that my application was accepted and routed to USCIS National Benefits Center for Processing with receipt numbers
Receipt Number MSC1791047742 and MSC1791047741 for both Form I-765  and Form I-131.

 

My humble request is can I merge both submitted applications into one so I don't have issues of intentional/deliberate submission or duplication of Forms I-765 and Form I-131 so as not to jeopardize my application and future applications OR whats the process/procedure to cancel one of the submitted applications.

 

Please Help so I don't jeopardize my Pending AOS.
