If I run the DDT and the target table is empty in the database I get 74 records (that's correct)
If instead the table has records in it (the 74 I just exported) the DDT says he has imported 74 records, but when I see the table actually only 20 exist.

The Deployment data package is configured with the Overwrite option (I expect to rewrite the whole table every time) and the table has a primary key made by two column (this last thing is perhaps the only difference between other tables that are working well)

What can the problem be?
