Identical emails displaying differently (invite / confirmation / subscribed)

[JohnAJ]

Something really weird going on!

At first, I thought it was a template design issue. I was creating 3 different templates based on the same template for Dada's invite, confirmation and subscribe emails.

The invite looked as it should, but the confirmation and subscribed emails were losing centering on the last element in Outlook (desktop). Outlook 2007, to be precise (not sure about others).

After a lot of testing and editing, none of which fixed the layout, I decided to upload the template unedited, exactly the same, to all 3 templates within my chosen email theme (invite_message.html, confirmation_message.html, subscribed_message.html). When I initiated these and saw them come in, I saw the same thing - invite was as it should be, but the other 2 had the centering at the end lost.

I can't see any reason for this other than something somewhere is adding or removing something!

The template I uploaded to all 3 for testing is the HTML generated at: https://mjml.io/try-it-live/templates/austin (copy at https://pastebin.com/57wJ3w4T).

The invite looks as it should: -

But the confirmation and subscribed have the last element incorrectly left-aligned: -

yet there's nothing different in the templates.
