Asset Category setup

Dears,

i just have a confusion about asset category.

i tried the following.

1) define new asset category and add asset cost account with cost center.

2) when i add a new asset and assign it to that category and create accounting.The journal show the same asset cost account but with 000 cost center. not with the cost center that i entered in asset category setup.

Please advice

Note: attached is a screen shots from asset category setup and the addition journal in GL.
