Hi @emmak109
Seems this question somehow similar to the other question you've asked
Audience selection for AA vs AB test - Adobe Experience League Community - 682459
So based on the your scenarios - can you try few options like
1) If the audiences for your AA and AB tests are not clearly defined and separated, there may be an overlap between the two, leading to users being diverted to the AA test instead of the AB tests, so review your Audience Definitions.
2) As mentioned in another post, Check your Prioritization for AB test and AA test .
3) Validate your technical implementation
4) If your AB test have very specific audience criteria like geographical / device type then eligible audience may smaller than overall site traffic so thoroughly examine your selection.
Hope this pointers helps.
Thanks
