Issue with mqtt old device name

I recently removed one of my Zigbee devices and then reconnected with a new name. When I look at mqtt broker it’s visible under new name but when I add to dashboard it’s name is still old and switching doesn’t work :frowning:
In zigbee2mqtt frontend it works
What could cause this?
How can I remove the device from mqtt broker (I wonder if this could be the cause)
