NumOpenPublicConnections Always returns 0

Hello guys, I am working with EOS sessions, and need to get the number of public connections to make a player start in a server that have one player connected, if fo not have one player connected to a server, this player will start a new server, but the NumOpenPublicConnections are returning 0 alway times. My dedicated server start a session, I registered a player, I can see it in the matchmaking EOS portal, the connections are decreasing in the portal, but when I try get the NumOpenPublicConnections I get a value 0.

int openConnections = SessionSearchResults->SearchResults[index].Session.NumOpenPublicConnections;
