I was able to extend the right column, but unfortunately it didn't help the "billing info" format like I hope it would. Can you tell me how can fix the "billing info" format problem? please see screesnshot above. Basically, the billing info is not displaying correctly at all. Thank you

Hi,

Is that a one step check out extension ? cause we do not develop it, so i don't know how does it work(billing template).
It has separate template and its independence with our template, please contact developer to get help.

Kind Regards
