>>10303781My store has the same set up.
I took all the Goo JitZu from the peg and put it on the shelf. I then removed the peg label and tossed it in the trash. I don't think it'll actually do anything but my assumption is that they just haven't put the 4 inch back because the Goo is still taking up its original peg place. This is a Target by work so I'm there almost every day.
