Can't view one number in my daughters text messages

When I click on the one number which happens to be her boy friend it will open another window and automatically select my oldest sons icon. I can view every number in her log just fine except for his. Had two different support tickets opened and they told me this is the last resort. Please help. The window that opens looks just like the window when you log in and select a child to view the log.
