I am in the army reserve, and rest of question inside.

Okay I am in the army reserve and my pay stubs have 3 diffrent debts in them, two just say debt and the third says enlistment bonus debt type 3, from the research I have done online the only way this could happen would be if I was demoted, changed jobs or was given anything other than a honerable discharge, however none of this has happend.
I am still working the same job, I have not been demoted, and I am defiantly still enlisted, the pay began to be messed up after I changed banks and they started depositing significantly less into the account, insurance and eveything has been paid but this is a diffrent debt I have no credit cards and I am absolutely not behind on any bills what so ever, and the enlistment bonus debt is for 5k and that is more than I was even given, If someone could please explain this or give me some clarity that they have just screwed up somewhere it would help put my kind at ease thank you
