Please Help - Strange Sims

[jaleosia]

I am sure this has come up but I searched this morning and could not find the answers. I have the basic game and Seasons installed. I was going to expand to a new neighborhood and make some new sims but when I went to place (the top right in the create area) the some of the sims displayed there, former downloads, have grey or black faces and some have white faces with little cryptic signs all over them including some of the hairstyles. Have I done something wrong? Also when I click on some of them a entirely different sim comes up. I know I am a computer idiot so I am reaching out here to try and understand what is going on.
Thanks for any help,
J.
