There is a thread on the Forums dedicated to DODMERB questions. You may wish to ask this question in that forum.
However, it looks like you will be receiving a request to provide more information about something in your physical.
You may have to wait for that information to arrive in the mail.
If you haven’t had an opportunity to thoroughly review the left-hand menu items in the DODMERB site, especially the FAQs and the process document from Deputy Director, Mr. Larry Mullen, I recommend it.
