Hi Pam,
This sounds like a bubbling issue. If you take a look at the rule condition under the 'Bubbling' section, I would try checking the second option or checking the third option and un-checking the first to see if that accomplishes the desired behavior:
If not, feel free to shoot me a private message with the DTM property name, rule name, and a URL to test and I'm happy to take a closer look.
Hope this helps!
Anna
