Friends List Bug

So... This has been happening quite a few times to my friends list. It gets bugged out and all of the people in the list aren't all in order like they should be (I have the option set to have them set by status). They are all mixed up and I cant seem to figure out why. If you would like to click the link below, it takes you to a screenshot of how this actually looks.

As you can see, the picture shows that I have sort by status selected, however it is not actually sorting it correctly. If anyone has a fix for this that would be amazing, as it causes me to get frustrated and restart my client for it to happen again 5-10 minutes later.

Thank you,
