Themes - problems with default theme selected.

Themes - problems with default theme selected.

I have created my own theme that removes the "Can't read or see images?..." header and left-justifies my emails so they DON'T go down the centre of the page.

I have discovered the following:-

If I create a new campaign from scratch, my theme works fine.
If I clone a campaign, it reverts to the default Zoho theme - BUG!
Even though the theme is changed in the newly-cloned campaign, it still uses the Zoho default - BUG!
Subsequent chain campaigns however, use the correct default campaign. Weird.
If I use Mail-In to create a campaign, again it takes the Zoho theme and not my default - BUG!

Can someone please investigate and fix?
