Preview looks different from artboard designs

When I preview my plasmic project both on localhost and web I have some buttons centered although they are left aligned in the artboard. My project id is qTsUfYzvMj33xizNJwAT7K

Hi @yaw_botwe, can you share also where we can see the issue/difference on the live published site?

Do you see the difference in preview mode (when you press the green play button in the toolbar)?
