Why a "Not Nullable" value is kept in a column marked as "Nullable" that was recreated after doing a full install?

Steps to reproduce the issue:

1. For a Study, configure for a specific Data Model in File Watcher a File Specification so that one column is marked as not null.

2. Upload one file with proper values in File Watcher Folder.

3. Note that the values are properly displayed in Data Management ->DataReview.

4. Edit the file loaded at step 2 and set the value for the Not Nullable column as Null.

5. Install Data Model in Full mode.

6. Upload again this file in File Watcher Folder.

The old value of the column is kept, no error is raised in DMW.
