Git in Dreamweaver does not recognize new files, unable to add and commit

Hello Community,

I added several new files in my Site but Git did not recognize them. They were not displayed green in the git file view. I coud not add or commit them. First I tried to delte the index.lock file in the git folder. This did not help. Afterwards I staged the files via add through the Git Konsole (Terminal). Git status shows, that they are staged. But Dreamweaver does not show this. The File names are still not colored in the Panel.

I would be thankful for any help.

Best regards,
Daniel
