I can\'t seem to get rid of untracked content in Git\'s submodules. Running git status yields:
# On branch master
# Changes not staged for commit:
#
This probably happens when you have another .git [hidden folder] inside the particular folder..
modified: ./../.. (modified content, untracked content)
make sure your sub-directory does not contains this .git folder.
If That is the case the issue can be resolved by deleting the .git folder manually from the sub directory.
