Lightroom edited photos become unedited version in iCloud

I'm struggling for syncing the edited photos from Lightroom to iCloud in my iPhone X (iOS 12.3.1).  The followings are my workflow:

1. Import a photo from iPhone's Camera Roll to Lightroom

2. Edit the photo in Lightroom and then save back to Camera Roll

3. Delete the original photo in Camera Roll manually

4. The edited photo in Camera Roll synchronized to iCloud Library automatically

I can see that the photo in Camera Roll is the edited version.  However, after it was synchronized to iCloud, it became the unedited version.

I tried to upload the edited phone to Google Drive and it worked fine.  However, for Google Photos, the same issue happened.

Anyone has similar experience before and could give some suggestions?  Thanks in advance.
