The revenue of a e-commerce site is only identified as Direct load channel sales, the site visits can be identified into different channel, such as paid search, referring domain, etc. I cannot display the real number of the report, but the report just look like below:

The issue happened for almost 2 months.
Checking the Create Marketing Channel processing rules , the rules looks fine.
So could anyone suggest any other thing will cause this issue and the way to fix it?
Thanks a lot.
