LIcense in MATLAB is different from license in LIsense Center

Is there any reason why my license numbers are different? After installation, I have activated MATLAB via login and password to my account and MATLAB seems to successfully activated the product on Linux. However, first, I cannot see any computers on which MATLAB is activated. Second when I look at license number in MATLAB and license number I received when purchasing the product, in License Center, the numbers are different!

I also install MATLAB on second computer (MacBook Pro) and I though the numbers are wrong, so I was trying to deactivate and activate MATLAB again and I eventually reached the limit having Error 354 :/ Now I cannot use it on Laptop!

My license is Student. I should be able to use the product on two computers.
