Advanced Alert Manager problems

I edited an existing template to modify a fixed disk % used alert. I also changed the subject of the email template in the actions and some other variables.  I save it and test it, but it keeps giving information in the e-mail subject line and performance monitor variables that I didn't want (from the old one).

Additionally, when I create a new alert with the same settings for the % disk space used and test it, the email is blank with none of the variables I put in.
