Application is not installed on your phone

Hi everyone,

I recently decided to convert some system apps to user apps so that I can greenify them with the free version of greenify.

Most of them were successful except for the following apps:

1. Hangouts
2. Music
3. Internet
4. Play Movies

I used the titanium backup feature to convert them. I did it for a bunch of others and they were all successful.

For the apps above that failed, I no longer see a directory for these apps in both /system/priv-app or data/app. They seem to have vanished?

I still have the shortcuts for these apps in my app drawer / home screen but they are the green android icon and when I click on them I receive the following error: Application is not installed on your phone

Would anyone be able to help me with this issue? phone is SM-G920W8 with android 5.02 rooted with cf auto root and TWRP custom recovery using stock rom.

Thanks in advance.
