I setup a couple of segments (just to test) and I would like to segment VirtualGoods etc.
But when I try to select the segment in the popup field that is what happen:
I tried with different browsers (Chrome and Safari) but both give me the same results (just to be sure that it wasn't a browser issue)
This only happens when you have no values in the segment you have just created. If you add a single value you should see that field populate.
