unique and ordered list from data obtained with formula

Goodmorning everyone
in the attached file I have a table in column A the data entered manually and in column B the same data but obtained with a formula
The goal is to extract the unique and ordered list of data
now with the formula I use I get the correct result only from the data entered manually (column A) while if I have to apply it to the data of column B (obtained with formula) it returns the first empty field ...
How to modify the formula in question so that the same result is obtained?
Thanks for your attention


Formula :

=IFERROR(INDEX([Origine],MATCH(0,INDEX(COUNTIF([Origine],"<"&[Origine])/([Origine]>"")-SUMPRODUCT(COUNTIF($D$1:$D1,[Origine])),),0)),"")

Thank you so much

or E2
=IFERROR(INDEX([Origine],MATCH(0,INDEX(COUNTIF([Origine],"<"&[Origine])-COUNTBLANK([Origine])-SUMPRODUCT(COUNTIFS([Origine],D$1:D1)),),)),"")

Hi+
thx so much for the support
The formula in column "D" does exactly what is espected
Unforntunately, formula in column "C" does not work when the first cell of the "Orig." is empty. If you try this in the file you attached you can see the result

Thx
