Hummingbird changing row padding/margin

Every time I activate Hummingbird it changes the page layout rows by removing the padding and margin I had added in.

If you look at the home page, where I have the statement - Call a Birmingham Locksmith not a call centre, turn on Hummingbird and then look you will see the row is now full height. It looks like every row is affected.

I am using DIVI from Elegant Themes and its hosted on my own dedicated server. The child theme has additional CSS and the footer info.

Any ideas - Osmond
