I found that if I don't close the files, the number does not change sometimes ???Hi Shafid, how are things down your way? ;-)
You're not the first to notice that closing tables is the most reliable way to avoid duplicates from multiple sessions. But there is another way: apparently any replace will cause latest data to be loaded. See

"... They ne'er cared for us
yet: suffer us to famish, and their store-houses
crammed with grain; make edicts for usury, to
support usurers; repeal daily any wholesome act
established against the rich, and provide more
piercing statutes daily, to chain up and restrain
the poor. If the wars eat us not up, they will; and
there's all the love they bear us."
-- Shakespeare: Coriolanus, Act 1, scene 1
