Klipper clipboard history repopulate itself after connecting to Android KDE Connect even tho it's been cleared on both

Hello, I’m new to KDE community, and I’m sorry if I bother everyone.

I have a problem lately with Klipper and KDE Connect.

Before I did any pairing with my android phone, klipper respect the delete button. So when I clear it and reboot it should not have anything in klipper history.

But once I paired it with my phone, the behavior changes, even if I clear both devices’ history, klipper somehow left with one clipboard entry upon reboot. I delete it again and reboot, yet it persists.

Klipper will only be truly empty if:

  1. KDE Connect is unpaired
  2. Clipboard sync is disabled
  3. One of the devices connect to different network which means they cannot pair.

I’ve tried:

  1. Disabling “Save History Across Sessions”
  2. Removing the contents of ~/.local/share/klipper/ (of course when plasmashell and klipper are killed)

Steps to reproduce this (as I remember):

  1. Pair KDE Laptop to an android device
  2. Copy something from laptop (It should appear on my phone)
  3. Delete all clipboard, to be sure delete on both devices
  4. Reboot the laptop
  5. Reconnect both machine via kdeconnect

Current Result:

Klipper will have at least one clipboard history

Expected Result:

Klipper should be empty

I don’t know how to bug report if it is a bug, so I want to ask here if anyone know what happened.
