All the built in notification tones are now gone after clearing the Media Storage app's data

The Album app on my phone fails to detect some of the pictures I have after I moved them. I tried clearing the Album app's data but it didn't do anything. After looking around the internet, I found that one way to refresh media apps is to find the Media Storage system app on the Settings and then clear it's data. After I did that, I noticed my notifications on some messaging apps stopped having sound. When I tried to select a new notification tone for it, I found out that all the default ringtones and notification sounds are missing. Is there a way to get this resolved like maybe there's a directory where these tones are placed in the system, or am I SOL? EDIT: After digging around, I found my notifications, ringtones, and alarm sounds are still in /system/media/audio/ but for some reason the ringtone selection dialog doesn't detect them. They don't have a .nomedia on the folder so it can't be that. Is there a way to force them to be rediscovered?
