It looks like the associated items were added months ago, though, and the .prop files are from November 18th. Do you think you were using the iOS app during those times on November 18th or the desktop app?
Basically, the .prop files contain invalid values, and we need to figure out which app created them, the iOS app or the desktop app.
If you paste SNAPJIY5 or the other item keys into the desktop Zotero search bar in All Fields & Tags mode, do the associated files exist on that computer, and can you open them?

What are the dates of the above .prop files on the WebDAV server?
Did you upload these files to WebDAV originally from the iOS app, from the desktop app, or something else?
