I think you've somehow answered that question already by yourself:
"...but let it because there's really nothing they can do about it."
I don't think the preds are that much focused on secrecy. Sure, they like to keep their secrets, but i don't think they give a fuck if anyone knows about their existence generally. As long as some human dirtbags don't get their hands on some pieces of their equipment, an event which would make them propably very angry, why should they bother? To protect our society from the shocking perception that we humans aren't alone in the universe?
I don't know... i think the yautja doesen't care about us that much. They stay stealthy on their hunt, but in general? We're just stupid humans, apes stuck on one single rock in the galaxy.
So they take this planet from the humans, and the humans can't do shit about it... they're just no danger on a large scale. If the Yautja want to have a small little "summer residence" for hunting in our own backyard, they'll just take it.
You're right, that would have been noticed by human goverments for sure.
By the way, i was surprised a israeli agent knew about the preds anyway... i mean, the story of a single "strange contact" by an us specforce squad finds its way to a foreign agent who isn't involved in any kind in a possible investigation about this incident? Either the CIA is very bad in keeping secrets, or there is some serious rumour going on about preds, and that doesen't sounds like a "single, non-confirmed contact" for me.
Nah, that's a really bad explanation, haven't slept for twentyfive hours and my concentration is dropping... but i hope you understand what i'm trying to say.
I'll even go one step further... maybe the human goverments don't just know about the pred's existence, maybe they're even supporting them, presenting worthy prey, or they're just not interfering with their "prey extractions"... not to be friends with them, of course not, but what's the alternative? So imagine the preds wouldn't have their own little hunting ground on some abandoned moon, what would they do to hunt funny little humans? Probably they would increase their hunting activity on earth. Not good. And the humans still couldn't do anything against it.
I know, this kind of speculation doesen't have any solid basement, but they're speculations, nothing more...
