Qusetion about druid tracking

[Poldarn]

So, I got my only character on the server to level 20 last night. It's a druid. I now have the track ability but for some reason the drop down menu for track sort doesn't work, it is grayed out. I am using the classic_old ui. Is there a reason for this? I don't know if this is a part of classic or if it is just me.
