Thank you for your help.
Is it the same "merge" and "allow multiple translations for identical source segements"??????
I think I always had "merge". (That is not the first time that something wrong with the TM happens, but I think I had allways merge).

If you have, and you do not choose "Overwrite" when you import the database, you will be duplicating your segments each time.
