Weird problem with tripple library folders

Hello all, I'm experiencing a strange problem with tripple library folders.
When I first installed windows I deleted all default library folders and created custom ones, all was fine. Some point later I decided to create a new library named "Music" (the same as one of the defaults). That's when things started going screwy.
At first everything appeared normal. I had a new folder called "Music" in my library and I proceeded to include folders in it. After I rebooted, though now I can reproduce this just by refreshing the explorer window, I noticed that I had 2 "Music" folders in my library. One had the default library icon, the other a music-specific icon. I proceeded to troubleshoot the problem.
Deleting either folder resulted in deleting both. Adding a new "Music" custom library added both again. Restoring the default libraries restored two copies of Music. I checked in appdata/roaming/ms/windows/libraries and saw that there was only one music.library-ms file. I then tried creating a new custom library, including all files I wanted, deleting the music library and then renaming the newly created on to music. This resulted in having 3 library files. -.-
I've been googleing but its hard to filter through the results since most are about having double the physical files inside a library folder.
Any help would be greatly appreciated.
