Camera uploads backuping up photos again

When i open the app, to have my iphone pictures uploaded to the dropbox camera folder i would click on the photos icon at bottom of the dropbox app screen on my phone. Then near the top it would say backing up photos and indicate the number of photos still being “backed up”. Meaning uploaded to the dropbox camera folder. I did understand that it should do that in the background but it does not seem it ever did. Meaning i had to open the app hit the photos icon and then it would start uploading only those pictures that i took during the day or since the last upload. Never really did in the background which is not really an issue. Btw When uploads are completed by the app it says all done backing up. Now the app shows and says running camera uploads scanning your photo library. Then it will show 8,300 plus images are being backed up. A few minutes later it goes back to saying running camera uploads scanning your photo library. As i indicated all but a few photos have already been uploaded a few weeks ago so it should only had to upload between 100 and 200. If i go to home icon it shows since my reaching out to the community 108 images and videos uploaded, 116 inages and videos uploaded, 2 videos uploaded and currently on 4 images and videos uploaded - all under the heading Today. Clearly if yesterday said 15k plus being backed up and today saying 8k plus being still backed up, 7k plus images where not loaded since yesterday based on the data on the home icon screen. I think the app is glitching and scanning the entire iphone camera roll and for some reason saying thousands of images have not been uploaded/backedup which is incorrect. However i also have an account on another phone and never had this issue on the phone and app.
