can't add subdirectory to project. I don't understand what I'm seeing in bitbucket GUI.

I am unable to add a directory to my project.   The directory name is bce_common, and is pictured below.  As far as I know, I have no submodules in the project. 

When I browse the source on the bitbucket website, I see the directory, and then there is an arrow pointing to a hash... I don't know what this means, and am not sure if this offers some clue about how I can add the directory to my project:

I still don't know what the problem was, but I was able to work around it like so:

1) mv bce_common bce_common2

2) git rm -r bce_common

3) commit -m "I have no idea why I need to do this, but hopefully this will enable git to see the directory again"

4) mv bce_common2 bce_common

5) git add bce_common

6) commit -m "add the module back to the project"
