Every time email is scheduled it overrides previously scheduled email

Hey there, here is my situation.

I have created a rules set to send an email to a cck field that is entered, and this is working well it seems.

I then created a triggered rule to send that email 3 days after the specific content is created.

This all works. My problem is that whenever new content is created it overrides the old scheduled emails. So, only 1 is scheduled at a time.

I'd be happy to go more indepth as to how I created each rule set and the triggered rule, but I figured I wouldn't go into an overloaded amount of detail unless that was needed.

Thanks everyone in advance!
