"Recent Edits" shows unedited phots, too?

I've noticed that the "Recent Edits" virtual folder in Lightroom CC shows now only photos in recently edited (it does), but also all photos auto-imported from the iPhone camera roll in the same recent time span — whether those photos have actually been touched in Lightroom (or Apple Photos, for that matter) or not.

Is this a known issue? is anyone else seeing this?
