Q: Recent call list

I opened up FaceTime on my Macbook Air earlier this evening, and at the top of my call log was the name of someone who I hadn't called but I also hadn't received a notification saying she had called me. The name does not appear in red, so I assumed the call wasn't missed. Her name doesn't appear in the call log on my iPhone either.

The only thing I can think of is that I possibly inadvertently called her? Is it possible to tell on a Macbook whether the call was incoming or outgoing?

Otherwise, what else could be going on? Did she maybe call me but hang up (and my laptop made a note of it but my phone didn't)? Is it maybe just a bug? Please help!
