iOS creates folder in iOS Albums with duplicate images from Camera Roll


My NC server is running on CentOS 7 and is currently on version 16.3. My iOS is running on 12.4 and my NC app is running on I have auto upload enabled within the app and have a destination folder set on the NC side. I only upload from the Camera Roll Album, but, I have noticed that an album called NextCloud is created when uploading and it basically has copies of the pictures that were just uploaded. This basically eats up space on the device. Is there a reason for the folder being created? Is the folder just storing image previews?
