Why doesn't Facebook show everyone that liked my fan page?

[Amir Brandon]

My page usually notifies me when someone new likes my page, and then when I look at the list of people that have liked my page, it shows their name on the list.
But there are some people who have liked my Facebook page, yet I can't see their names on the list of people who have liked the page, as if they haven't liked it at all. It's been a few days since this has started and it has not changed. Does anyone know what's going on? Thanks!
My fanpage is https://www.facebook.com/pages/Amir-Bran...3059106230
If anyone's interested
