Am I overthinking it or do they really dislike me?

So my daughter is apart of this really well known group that I'm sure you will figure it out by the end of this note. Well at the beginning I met this one leader of the group and at first she was all nice and very welcoming but then another mom came and started to misidentify me as someone who she knew and had an issue with in another state that I had never been to before. So, the leader approaches me asking some questions about if I had lived in another state, worked at so forth and so forth etc. which I in return answered honestly no. So, that conversation was done and moved on.

Well ever since then the leader hasn't been very chatty with me as she is with the others and gives me a vibe that I had done something wrong or just has no interest in making small talk with me. So, my question is how would you have handled this situation and does this mean that she didn't believe me or am I overthinking everything?

I'm usually good at socializing with people in person but this ones got me stumped and I don't know whether to address it or not.
