&#x displays instead of currency symbole "letters"

I commented the other countries in the list of countries in MP after adding my country to that list.
And I did the same to the currency list.

But when I create a new site with New Blog Templates, I get my country selected but a list with the option to select an U.S.A state also appears under it, and I get "&#x;100" instead of "D.A. 100" in the currency symbole position choice and on all other places of the backend and fronted where the currency symbole should appear.

I don't think it's a problem of NBT, so I'm asking you where does it come from ?

Actually, I just have to click and save the MP settings in that Site in order to get everything back to normal.

But is their a way to fix it once for all so that I don't have to interfere each time ?

Thanks in advance.
Cordially, Mounir
