which variable does Pinnacle 21 Enterprise use to create the “Issues by Treatment report” when validating ADAM data package?

I have a question for the P21E “Issues by Treatment report”, for validating ADAM item11 package validation. From the reported value, it seems to display by the ADSL.ACTARMCD or DM.ACTARMCD.

But the frequencies are not exactly the same as the ADSL.ACTARMCD or DM.ACTARMCD. Please see the difference between the P21E reports and the ADSL.ACTARMCD frequencies below. Is there any reason why the frequencies do not completely match? Thank you.
