My Endnote library strangely continuously, with no end, keeps on uploading the same reference to it. So far it is uploaded it over 60,000 times in less than an hour and has not stopped. The process of doing so creates intense lag to the point of rendering the library unuseable (I can’t even delete one of those copies!, and in the process of trying, thousands more are added to the library). I think Endnote is trying to sync the library at the same time.
None of these continuous reference copies are present on the library when viewing it on EndNote online or on my iPad.
I had added the reference some weeks ago, but have used the library since without problem. This only occurred today evening, even after using it in the afternoon without issues. I did not attempt to upload that reference in that afternoon.
Opening and closing Endnote makes no difference. The EndNote library is on my Dropbox, and strangely the references remain when upload an older version from a few days from Dropbox, even when those duplicate references were not present then. This is using Endnote X9.2 on a MacBook Pro (Retina, 13-inch, Early 2013) with macOS Mojave version 10.14.6.
Any help would be appreciated, as otherwise I’ll be unable to use this library on my computer.
