Steps to reproduce the issue

1. Move to System - Site Templates -

2. Take a close look at the button bar (From Save to Close File)
   

3. You see the buttons Delete File and Close File directly adjacent to each other and both displayed with red background.

Expected result

The buttons should be displayed at some distance from each other and with different backgrounds.

• The Close File button should be displayed in third position (after Save & Close).
• It should have a background associated with a warning (i.e. orange).

Actual result

You might accidentally click the Delete File button when you just want to close the file.
