You are getting no answer because you posted this question in the wrong place. The Champion program group is about the champion program. Your question should be posted to products. I recommend you move it there
Now, I am not really sure I understand the problem you are facing, but a thing you need to remember is that using additional filters in the smart campaign in the program is not the right way to prevent a content to be sent, because the engagement program will still call the smart campaign an count it as a sent with regards to the exhaustion. This may explain your problem.
