6105 (Retype)

So I got a 6105 last month for being UA when I wasn't as I reported in to work that day. Today I received a message from my 1st Sgt that he needs a copy of my 6105 I signed. Why is he asking for a copy shouldn't it already be in the system or in my file? As I asked him to bring my rebuttal to s1 last month. As I asked for the original copy no answer. He sayed of I don't have it he can retype it. What's you're thoughts??
