Shelve doesn't work for Added files
Created originally on Bitbucket by datallah (Daniel Atallah)
If you have a file that has been added, but not yet committed, the file will appear in the Shelve dialog, but attempting to actually shelve the file will do nothing.
Any other files selected at the same time will actually be shelved successfully.
To upload designs, you'll need to enable LFS and have an admin enable hashed storage. More information
