[Koha] Item display status text

Dear All, After I changed the 952$7 subfield of the items to "Not For Loan"(Chicese mean "不外借"), The status text of the item is displayed as "不外借 ()(不外借)" in the Chinese page(attached picture1), But that "()" is extra and unnecessary, it should be displayed as "Not for loan (不外借)" like the English page(attached picture2). I went to Koha Translation website to check, but I didn't see any translation with the extra "()", how can I make it display as "不外借 (不外借)" ? Sincerely, Atron Chen
