SOURCETREE not sending modified files to server?

Question

git

Set up SOURCETREE with git on beget hosting.
From the hosting, everything was loaded successfully on the local PC.
When changing files locally, I commit and press send. And for some reason, only git files are sent to the host (as it seems to me). if, after sending, click git status on the hosting, you can see that you need to commit.
If I changed something on the host, then SOURCETREE receives both files and git files.
