Cloned Public Github Repo inside Wordpress plugin Does not Commit to Private Github Repo

I'm using PHPStrom 2017.3 to develop a custom Wordpress plugin.  The plugin directory is housed under c:\inetpub\wordpress\wp-content\plugins\*myplugin* and I cloned a public Github repo into a subdirectory therein.  All the files from the public repo downloaded without issue.  

I committed the Wordpress plugin to a private Github repo and see that the cloned directory was copied to Github but no files are contained in it.  I checked the Version Control settings to ensure that the subdirectory is not being ignored or excluded.  What other steps should I take to upload the subdirectory properly to my private repo?

Greatly appreciate your help and guidance.
