Improper alignment of WHMCS using WHMCS Bridge

Hi,

I recently came across this plugin to integrate website template with WHMCS. So i installed the free version to test.

As you can see in the above URL, the alignment and design of WHMCS is not proper. I tried to make the template as “full-width” but it is of no use.

Can someone let me know as to what is the issue and how to fix it using the free version ?
