Android App Will Not Automatically Upload Pics or Vids

I can manually upload images through the Nextcloud 1.4.1 app from the Android store on Huawei 6p running Android 7.1.1. Using Auto Upload is not working.

When setting up Auto Upload, no files upload to the directory I set. Instead I get many, as in tens to hundreds, of 20k or so files that are not the same names of my images.

The file names are just numbers with some of the file names starting with a hyphen, as in a negative number. I have no idea what these files are. When I look at my Camera folder, files start with either IMG or VID. There are no files that begin with numbers like what is being uploaded with Auto Uplaod.
It doesn’t matter if the source is my Camera folder or another folder like Downloads, etc. The Nextcloud app just uploads all these tiny files that don’t seem to have anything to do with the files in the source folder.

Looking at the Uploads folder on the app, lines there show successful uploads. However, they are successful uploads of all these strangely named, 20k files and zero images.

Also, I’ve found no way to stop the upload of all these bogus files. When I disable the auto upload for the source directory, eventually the uploads stop. But it takes several minutes before I notice it stopping. I have to force quit the app if I want the uploads to stop right away.

I just wanted to see if I could get photos to upload reliably. So far, this doesn’t work.

I don’t understand why they Auto Upload will not put files in the same place that I can upload files manually.

Is there a new version where this works? Is this a problem with this version of Android?
