Even though the results don't show the Level 120, Sara is actually Level 120. All I had to do is go into the Single/Multi Lobby on a different CAC that doesn't have a mentor. Then I'd go into a PQ and pick a particular CAC for that PQ there. I wanted to do that because I feel having a mentor showing up just defeats the purpose of it being a Solo PQ run even though AI Ally teammates are usually bad.
