Problem with Numark CC-1 carts and stylus

I have 2 numark cc-1 cartridges. I just received 2 styluses (styli?) for them. One cart fits perfect, the other one does not look like it is seated correctly and sounds like shit.

Does anyone have any experience with that? I am going to guitar center to get them checked out, but I am just wondering if anyone had some quick advice.

Thanks in advance.

Return them both, spend the extra 40 bucks and get a pair of ortofons. The gods will thank you.
