My concealed carry permit applictaion was denied???

[40calkid]

I bought my handgun about 2 weeks ago and everything was fine with my background check. I sent my app. for concealed carry 7 days ago and i got a letter today saying my app. was denied or classified as undetermined but thats all the letter said it didnt give me any reason at all as to why it was denied. I have a clean adult record. But when i was under 18 i had a couple underage drinking charges and a marijuana charge but i was never convicted of a felony or ever spent any time in jail and this was all before i turned 18. i was in the army and had a general discharge on good conditions. i have an appeal that im sending out today but i need some guidance on why i would be denied my permit but allowed to buy a gun??
