Can't delete album in Pictures app on Lumia 920

Question

I used my Lumia 920 phone as a flash drive for random files.
One time I uploaded a folder of music files to: My Computer\Windows Phone\Phone.
Then, one day I opened Pictures app and found new album there. It was called "Artwork", I deleted it, but still whenever I open Pictures app the album's still there, just empty. Tried deleting that folder trough Windows Explorer, but no luck, phone still shows it, though it is deleted.
Tried creating folder with same name: no music, just one random picture, and phone showed it (not creating a duplicate Album) then renamed that folder, it magically renamed in picture app too! but then again, deleted it, and it is showing up empty with different name now.
By the way, the folder "artwork" was inside the folder of songs, so in picture app it was "folder in folder"(maybe thats the bug). Something like: My Computer\Windows Phone\Phone\Group name\Artwork
This is good example of what problem I have:

Answer 1

I've created an account just to post a solution! I'd had the same problem for weeks and I finally figured out a solution today:
(Don't forget to exit the "Photos" app using the back button before connecting the phone to a computer)
1. If you haven't deleted the album folder using a computer, do it (open the phone memory on a computer and delete the folder).
2. Create a new folder and give it the same name as the album in question.
3. Copy a new random picture into the folder.
4. Unplug the phone and make sure the new picture's showed up in the gallery.
5. Connect the phone to the computer again and rename the folder to some gibberish, a single letter (like "a") is enough.
6. Unplug and make sure the album's name's changed in the gallery as well.
7. Connect the phone again and rename the folder to "Sample Pictures".
8. Unplug and check the gallery again, the album should be named "8".
9. Tap and hold the album and delete the sucker.
The steps above worked for me when nothing else had. Steps 3-7 are mostly just check-ups, they might not be essential but they indicate that you're doing what you're supposed to and that everything works as expected.
