i am interesting to continue this discussion, can i answer it my self ? because i have same problem as @SaulTJ The banner with ID 1332 is linked to 5 zones, yes?
i have 3 banner , 2 banner (type campaign = contract) linked in 1 zone another is remnant linked in same zone .
the probability show 95% for remnant and contract 5% witch each banner get 2.5% for contract.
Are there other campaigns in those zones as well that do have probabilities > 0%? no
Are these campaigns higher priority, and are taking up all of the available inventory? not sure i just have 2 campaign type remanant and contract in 1 zone
Are there any remnant campaigns that are seeing any impressions in the zones? nope still 0 impression
