Continual out of sync alerts

I’m syncing from an Android to Windows. Android is in SEND ONLY mode, Windows in RECEIVE ONLY.

But during the syncing I’m continually getting OUT OF SYNC alerts in the Windows GUI. Nothing (that I’m aware of…) is modifying the files on Windows, so what might be causing this?

v1.18.1, Windows (64-bit Intel/AMD) 1.18.1 Android

Could you take one of such files and compare what exactly differs between the Windows and the Android side? Has the content actually changed, or is the difference limited to something like a timestamp or similar?

If possible, please upload screenshots showing the Syncthing Web GUI from both sides, with the errors visible too.
