Hi @Anna Adezati
Are these 10 columns created manually?
Please check if there are some hidden columns set to shown among the 10 columns: column settings> show/hide columns. Those hidden columns will not be in the form when you try to insert a record from the + button, even they have been set to shown in the view.
What's more, some columns could not be edit manually such as calculated columns, so they will also not appear when you new an item.
