Working with GIT via bitbucket. Not everything loads, how to fix it?

Question

git

Working environment -
1. Production server (shared hosting, it has git, but no composer and can't install it)
2. Development server, home, git and composer are.
I am developing a small website in yii. Due to the fact that there is no composer on the production server, I upload all components from the vendor folder to git.
Everything would be fine, gitignore is cleaned up so as not to remove the vendor folder from the commits. The first commits were successful, all components were loaded (I remind you that composer takes packages from github, but I work with bitbucket). The last commit gave the following picture:

What do the folders highlighted in gray mean. What does the arrow and commit hash mean? And why the folder became inaccessible and when git clone on production - empty.
Thanks
