Git Submodule still shows up after Deinit

I took the following steps to completely remove my submodules: Link

Everything is gone, but it's actually really annoying that when I browse the repository on Github, it still shows the module, but it's grayed out. Is there a way to get rid of it? It's just super annoying to see it's in there when it really isn't ...

I have:

• Removed submodule entry from .git/config
  
  
• Removed submodule directory from .git/modules
  
  
• Removed entry from .gitmodules
  
  

Github recognizes that it has been removed, but it still shows it on Github as a hidden Submodule.
