It is a Mini PC Windows 10 Computer Stick Intel Z3736F CPU Up to 1.83Ghz, 2GB Ram 32GB Rom. The Bios is American Megatrrneds and states the Core Version is 5.008 though at the bottom it says "Version 2.16.1242". As far as the device, Amazon says it's a "T10009-001" but to be frank the only item number I had before was the Z3736F. See link here.
You are going to have to contact the manufacturer top get more information on what is going on. If the documentation (or simply the box) that came with it, there must be some information about the manufacturer. Alternatively, contact NEXBOX (the seller) and ask them for contact information.
Hope this helps,
