Magic trick with palmed values…

Hi,

I added 5 new names in a base and it is impossible to see them.

Even if I sort my id raws in ascending order this 5 names are not displayed…Their id numbers are missing.

But if I launch a search, I find them ! And I can see the id.

What can be this magic trick ?

(All the columns are without special settings)

Thank you if you can help.
