Facebook Page posts automatically sharing to groups

Is anyone else having this issue with Facebook Pages? Whenever I post an image on my Page, Facebook automatically shares it to relevant groups. I am not a member of those groups. Is there a way to completely turn this off so my future posts stay only on my Page?

Facing the exact same thing recently, and it's super annoying. It feels like Meta is pushing the cross-posting feature automatically without letting us opt-out easily. Let me know if you find a fix for this!

That's the "Public Content" / cross-posting suggestion feature, not a bug, check Page Settings and Privacy for a cross-posting/content sharing toggle, it's usually off by default so worth confirming a group admin didn't opt your page in from their side.
