I can turn the lockring by hand about 1 time before it starts to ratchet/click. In contrast, I just put my old cassette back on(it has one separate 13t cog), and it sits nearly flush with the end of the freehub. I can turn it's lockring by hand about 1 3/4 to 2 turns before I hear a ratchet/click sound.
Yhe last sprocket isn't on all the way. It's hanging on something. If it's on right you can push it fully against the one before and compress the cassette with hand pressure. BTW- please tell me that you don't have the last one on upside down.
