Settings
- I forgot to press SYNC after ending up the session, and I turned off the DAU

Data extraction
- I can see only one SD EDF file in the processed files, and the file does not include the montage I chose.

- After renaming a session, the annotations in the EDF file are as the previous name.
- I cannot see any signals on the display screen.
- When I press on ‘Move’, nothing shows up.
- I have created a dataset with an identical session name; how can I have a distinction?
