Permission issue

My players are receiving a message saying: “You do not have permission to run the macro: simpleCalendar”

This happens despite the players having the proper macro permissions in the configuration. All other macros run fine but this one fails. It is for simpleCalendar. The funny thing is, if they create the macro and run from the hotbar it works, but the active tile they click on does not work.
Thanks

Found a solution: Go to Monk’s Active Tile Triggers tab under Configuration Settings and turn off “Use Core Macro Execute”.

Why that works, I have no clue as it is supposed to be on in case of problems. Anyway, thanks.
