Why do I see the message “Not defined” instead of a direct ad in the metric?

Question

Yandex.Metrica

In the metric filter, the following is set: "Sources - Tags - UTM Term" and "Sources - Direct - Yandex.Direct Ad". Instead of part of the declarations, I see "not defined". Why might this happen? Do I understand correctly that the point may be that the ad comes from two direct accounts, and I was added to only one, and therefore I don’t see ads from the second account?


And if I look in "Standard reports - Sources - Direct, summary" then there is no phrase in the "Ad display condition, Search phrase (Direct)" that does not define an ad in the previous report. UTM Term and Search phrase (Direct) - is it the same thing? Why then the information from the reports diverges?
