[tor-relays] Relay no longer acting as a gaurd node?

Hi All, A little while ago one of my relays switched from usually acting as a guard node to never acting as a guard node: https://metrics.torproject.org/rs.html#details/9715C81BA8C5B0C698882035F75C6... Doesn't matter to me if it's a guard or not jsut want to understand what's changed and if it's a problem. Do I have a misconfiguration? -Jon
