Known issue - Member unique name is displayed incorrectly

For the Member field, even if you select Pass name to pass the member name when users click the Action button, the Action button configuration page (Set parameters) still displays the member unique name (MUN) instead of the member name or alias.

Workaround

To work around this issue, for each action button that you saved where you specified Pass member unique name for the Member field, edit the control details for member list, explicitly set Pass member unique name for the Member field, then save the book to preserve this setting.
