Looks a bit weird your screenshot!
Your phpscm version?
One thing I noticed. There is a problem with that when you try to change the contentpart from e.g. plain text or images or whatever to a plugin. In this case it shows you the mask for plain text not the plugin. Seems to be a bug!?

You should change your profile language to english, I can not PM you, there seems to be some problems with your swedish settings.
