Here are my settings:

    - batch import:
          [ ] Scan all directories for files
          [x] Avoid duplicate songs
          [x] Update songs if matching files are found   (that's my usual setting, but I also tried with this turned off and had the same problem)
          [ ] Automatically crop pages

          Title:  Use Filename As Title

          I also specified values for Artists, Genres and Albums; the other groups were left unspecified


- under Import Settings, all four options are unchecked

- for Storage, I have the following:

[x] Let MobileSheets Manage My Files
storage location: /mnt/sdcard/MobileSheets live data
[x] Expose Database File
[ ] Delete Original After Copy
[x] Create Subdirectories For Songs
[ ] Copy Audio Files
[ ] Add Unique ID to Filenames

- Render Preference is set to quality
