Glitch in Responsys?

I'm new to Responsys, but have gone through several tutorials. Yesterday I copied a campaign email and saved it as a followup email into the same folder. I edited that html for the followup and saved changes only to that new html. I looked at the original html email that I had sent out last week and the changes I made to the followup email somehow were made to the original as well. (all 3 versions)

Today, I opened a new and different campaign. Created a new folder, wrote the html, created a list and filter, and saved. Looks beautiful. I then went back into the campaign I worked on yesterday only to find the new campaign now appears in this folder as well.
