I want to add the company "Airbus Group" to my dataset https://wikirate.org/Biggest_french_companies_key_financial_numbers.

I click on the 'edit' button of my dataset, then I click on the button "Add item" at the end of the list of companies already added.

Then I find the company I want to add (Airbus), I selected it and click on the button "Add Selected".

And then, when I click on "Save and Close" button at the end of the edit window, The rat appears, with a 500 Server error.
