I found it so weird that my mobile PDF that I've added signature and than shared the PDF with a recipient. I noticed that I've got a duplicate. I don't know why didn't the PDF that I've signed upload when I went to share it with someone. So I deleted the version I've "Save to Adobe cloud storage" and kept the shared version. The one I have on my mobile device I kept also.

This is so confusing. Even Google Drive and Dropbox and iCloud Drive wouldn't create duplicates. It's either sycned up and on the devices I just remove the download and the file will remain in the cloud.

It's counterintuitive that this process even exist and it shouldn't be happening.

I'm frustrated because I can't tell what's the version history if it is creating duplicates to begin with.
