Categories import fails using .csv or .xlsx

[toimata]

Hello,

Since 3 days, i have some troubles to upload categories in my website.

You can see a capture of the import file : capture_fichier-import-categories.jpg

The import looks to be successfull (capture_import-categories-termine.jpg),
but when it's finished, the categories are not visible on category list (capture_liste-categories.jpg)
or product page (capture_fiche-produits-02.jpg).

Does somebody had this problem ?

Thanks for your help.
