What users show up in Manage Users on the mendix developer portal

On my app we use MendixSSO for our accounts. I went to go remove a Mendix accounts access to the app, I went to manage users and noticed that it was only 1/10th the amount of actual users that use my app. Im very confused by this because we use the manage users feature to invite users to the app. My question is why are not all the users showing up and only a given few?

This is resolved just turned out to be a bug on the Mendix portal side.
