What went wrong?

Hi. I just went through recruitment at a school with 10 chapters. It is a public college, and I am an in-state student from a big feeder high school. I ended up going from having the max of 8 houses for round 2 to being dropped by every house except my dead last choice(who I'm pretty sure invites back almost everyone, at least for the first few rounds). When I got back my schedule that day for round 3 with only that house, it was devastating and I dropped out immediately. I know that we can never know what goes on behind the scenes, but I wanted to get some thoughts from others about what could have caused me to get dropped by all the chapters.
First off, I was a legacy for two chapters. One of them had a policy at my school that they invite back all legacies to at least the first invitational round, but they dropped me after round 1 anyways, which was super weird. For round 2, I thought I had some really good conversations in some of the houses and was feeling pretty confident by the end of the day. That's why I was so shocked when they all dropped me. I thought I had had great conversations and had presented myself well. This was philanthropy day, and I had asked questions and had told them all about my service work in high school. I just have no idea why they would have dropped me after all of this. My GPA is very high, I had recommendations for most chapters, was a legacy for 2, am in-state from a feeder school, and knew a lot of girls within about 6 the chapters. I even knew 10 girls in one of the houses but they dropped me after round 1. None of this makes sense to me, and even my Gamma Chi was as shocked as I was. Anyone have any thoughts?
