GarageBand pitch correction plug-in?

In GarageBand, I used the Pitch Correction tool on four tracks of a song I made. Today I went back to the song to record another track, and when I went to add the pitch correction under plug-ins, there was no option for it. On the other tracks, it says that they still have pitch correction, but there's no way for me to adjust it. When I click on the plug-in, a pop-up appears, saying "This plug-in provides compatibility for certain patches and loops. The full version can be found in Logic Pro." Is this plug-in no longer available?
