Database new scripts


I made a database restore and when I run Cuba Studio I have 3 new scripts that was generated automatically.
If I let Cuba to update these scripts, I have errors.
I’ve removed all files from below folders and also I use Clean (remove the build folder).
The only solution that I found (in order to make my program to work) was to move scripts in update-manually folder.

Where (why) come from these scripts?

They come from the difference between database schema and your current data model (entities).

And is a right solution to move them in update-manually folder (in order to get rid of them)?
I told you the program works without these scripts in my case.
