Sip rim tubeless

Hi guys (sorry for my english), I bought two rims tubeless Sip (code 81015000) but arrived a little different: one has premounted valve on the centre (and it' s ok, same as others I had bought in the past) and the special nuts in the box, while the other is without valve, with the hole in the side and came without nuts. I never made a return process. How I do? I have to send back only the second rim, or both? Thanks.
