System monitor-IPv6 address display not correct

I have a problem with IPv6 address, fe80::22c4:6f81:57df:d65e%eth0. The result has a suffix %eth0 and not clear when display in hass. How can I omit %eth0 in the display? This is my configuration:

  • platform: systemmonitor
    resources:
    - type: ipv6_address
    arg: eth0
