I've tried the "contains" option and because it also recognizes bits of a tag, I don't think it's a good solution for me. With the "is contained in" it recognizes everything it's supposed to and none of the others. I thought (based on the tooltips) and your post here:

I've attached the csv and log file for the run I just did.
