Import "accounts" not working totally ... ?

Hello there,
I have a weird problem with the import.
I have made export from SugarCRM to accounts.csv.
Then I change to accounts.txt

I can correctly display all the datas.
If I import, the columns are corrects.

I have made this operation for “contacts”, “leads”, and some others.

No problem.

For this one, accounts, some datas disappeared after the import, like random phone numbers and others street adress…

Anyone has a clue on it ?
