Not able to use MDT with license issue

What FivePD version?

1.0.3.1 (Most Recent)

What issue are you experiencing?

Me( BaconGamings) unable to use MDT from what I suspect and have proof of it being due to the fact that me and my brother (DirectorMichael) have the same License Key.

Please explain in detail what you're doing for this to occur

So, when I first enter the server and create a department, no issue. I'm now in the MDT. But when my brother joins it decides that since we both have the same license, it is unable to create his "user" so it assumes we are both the same user but because it assumes this, it denies us both access to using the MDT by saying "You are already in a department" which is true but why did it exit me out then? In the last photo, the other two id's are just friends ID's neither are my brothers ID, which is why they were blocked out. An example below of what I'm experiencing:
