Launcher Bug

In the Twitch App, I click on any of my other modpacks to try to open them, and the launcher comes up. The only modpack it shows is TerraFirmaCraft (NOT the one I clicked on), and the latest release of minecraft and the latest snapshot. So I've tried removing the TerraFirmaCraft from the launcher, and now it only loads up the latest release and latest snapshot. (Keep in mind I'm still NOT trying to open TerraFirmaCraft AT ALL) I've tried restarting the Twitch App, still does the same. I've closed all instances of minecraft as well, still nothing. Also, when I try to start TerraFirmaCraft itself, I can't join a world, nor make a new one.
