Is the behavior still occurring? Is it occurring with other notes?
If it occurred only with one note, and only on one computer, it sounds more like a Sync issue than a Ctrl-X issue.
Does your desktop computer have some other syncing software running as well, such as Dropbox, OneDrive, iCloud, etc? Two services (Obsidian Sync plus something else) both trying to sync the same files at the same time can cause issues.
