Apps on SD card not showing app drawer or in the On SD Card section in Settings

Recently I had moved almost all of my third party apps to the external SD card. Now suddenly I can't see any of those apps in the app drawer. I can see the SD card is showing up in the ES File Explorer. I am using Blisspop ROM and everything was fine for the past coupel months.

Is there a fix for this? What's going on here?
