New annotations disappear after restart

[ruiz-manuel]

So I made my dataset as follows:
1.- Make dir in datasets folder and put images in.
2.- Import a json file with preannotations (from a DL model)
3.- Modify annotations

My problem is that whenever I retart the server, all my annotations go back to the state of the first imported json.

How can I prevent this?
