Direct Channel Numbers are Higher than expected
Hi Team,
Please Help me with the following doubts.

1. My Direct Numbers are so high compare to other channel that is not expected coz most of the traffic should comes from campaigns
2. When we break down to understand the direct, I can see other domains like Facebook and google. Is it right way to breakdown and if yes why we are getting other domains in Direct channel.
Pleas find my Marketing channel processing rule order for your reference.
3. Do we need work anything on Internal URLs, Since we are tracking two different site(sitea.com and siteb.com) of the same org in this one report suite, Internal ULRs
I would like to know the why it is happening, what could be the root cause for these?

Direct Config:

Internal URL Filter setup:

Thanks!
