Hello. I am experiencing inconsistent vertical gap in my email in Outlook 2013 120 dpi in Litmus. If I run the test more than once, the gap will sometimes show and then sometimes not show. Here are the images Outlook 2013 120dpi & Outlook 2013 120dpi. This was the code used in both images, and once again this was not changed. The Litmus tests produced different results when run more than once:
