Github graphql – memebersWithRoles does not return all members on organization

Using graphQL for github, I cannot get the full set of members in an organization.

Using this GraphQL I get 45 users:
query
{node(id: "#@#@#$@#$##$#@") { … on Organization {
membersWithRole (first: 100) { totalCount nodes { login id name createdAt, updatedAt}
}}}}

and same with this one:

organization(login: "OrgName") {
membersWithRole(first:100) {
totalCount
nodes {
name
login
}
}
}
}

But when I go to People on the org, I see 54 users. How can I get all users/members in an org.
By the way, a few of the users that do not show up as memebersWithRoles, are working fine and pushing/pulling all day long.

The Organization is not public.
