"Save As" does not work in ubuntu

When I select "Save As" for a new score in ubuntu, it goes through all of the steps, but no file is saved.

And the directory selection does nothing. The save command always saves to my home directory, independent of the directory selected.

If I move the score to the desired directory and open it from there, the changes are saved back to the correct directory.

And I can't seem to create a file with a name that's different from the song title, but that may be cockpit error. I opened a file, made some changes, did a "save as" and the changes got written to the original file. I had to change the song title to get it into a different file.
