User role is not set correctly (alanning:roles)

Roles.userIsInRole keeps returning the wrong value although the role is set. Any idea whats wrong??
(if i check the role in the client-side console it returns true…)

FlowRouter.route('/secret', {
  name: "secret",
  triggersEnter: [(context, redirect) => {

    if (!Roles.userIsInRole(Meteor.userId(), 'sec_clear')) {
      console.log(Roles.userIsInRole(Meteor.userId(), 'sec_clear')); //returns false although role is set...
  action: function(params, queryParams) {
    BlazeLayout.render('nLayout2', {
      footer: "fx2",
      main: "secret",
      nav: "navigation",
