Lightroom Album in iCloud

Could you clarify what you mean by "uploaded photos from LR to the iCloud"? LR uploads to the Adobe cloud, not Apple's iCloud. Unless you mean that you export the images from LR to the device's camera roll (i.e. to the devices Photos app)? If that's the case, then I would expect to see photos exported in that way to appear in Photos in a "Lightroom" album (and that still happens when I do that). As for getting the images up to the iCloud, that's something you'd need to check in your device's iCloud settings menu to make sure that you haven't disabled the Photos option in the iCloud settings. I keep that option disabled on my iPhone and iPad, so I can't check how they would appear in the iCloud after uploading.
