Adopted Internal SD Card is mounted twice
Edit: I FOUND A SOLUTION. Using Solid explorer navigate to /storage/emulated and then open up the properties for the folder titled 0. Three dots in the top right corner and select "hide media" if it gives you a toast message saying there was an error, just do it again. So far Solid explorer is the only application I've found to give the solution. I'm not 100% sure what it's doing to the folder but it's working. 

Any luck with this? I found found the same issue. If you could find a way to blacklist the mount point from the media cache it should work
