Look at the parameter associated with the tooltip. Now look and see how you use this option to filter queries in your report. If you have a filter installed: -
[namespace]. [table]. [column] =? MyParameter?
... then it doesn’t matter that your invitation is an invitation with several choices, it will still be executed as a single invitation of choice. Change the filters so that they have the form: -
[namespace]. [table]. [column] in? MyParameter?
