Disconnecting Tradfri On/Of switch from power points

This isn’t really a Home Assistant question, but hoping someone can help.

I have just bought one of the Ikea Tradfri On/Off switches, and I’ve been able to pair it with Home Assistant via ZHA, however it has also paired itself directly with all of the Xiaomi Zigbee power switches in the house. I don’t have a Tradfri hub, and it is still able to turn all of the power switches on and off even when HA is offline.

Does anyone know how I can unpair it from all of the switches? I’ve tried repairing it with HA (pressing the link button 4 times), but that doesn’t make a difference. At this stage the switch is useless in this state.
