That’s a feature. It’s showing you the title of the post in world, and the packaged up source of the cross post with its title in Canada. The two titles are not required to be the same, so showing them both is appropriate.

Isn't this just designating it as a crosspost? That's what I've always interpreted it as anyways....

That is the normal way of showing crossposts in Voyager.

It makes cross posts obvious so I don't mind it much but I would also probably select a "Hide crosspost titles" setting if it was an easy addition

Turn off the ’embed cross posts’ option
