So I am a web developer and less email developer. I know the key is to use tables. Our team, without consultation of best practices, approved a email template which has a top image as a background but also an overlapping table that cuts on top small portion of the top table. I started creating this Litmus but of course MS Outlook 2010, 2013, and 2016 is not displaying correctly. Does anyone know how I would make those two email engines.

Not sure if the Admins of Litmus has access to view all email builds but here is the link:

I am also having issues of making those two columns stack on mobile screen view port, so any assistance on either of those issues would be most helpful.

here is a image as well that explains the overlapping design I am eluding to:
