Problem with BBCode

Hello everybody ,

I would like to integrate on my website the BBcode plugin.

The problem arises when i add on the toolbar ['JustifyLeft','JustifyCenter','JustifyRight','JustifyBlock']. Indeed, they are not translate into BBCode unlike "Bold" which becomes [ b ]sample text[ /b ]...

Have you got a solution for me ?

I hope to have been clear enough and thank you in advance for your help.
