This scanning message alerts you to the fact that minicalendar tokens of a particular facing pages spread of a given template are based on different DayValues.
In the image on the right, the minicalendars are meant show the current month and the next month,but having chosen 1 as DayValue for your minicalendars, you would have [1mc+00] on the left page and [1mc+01] on the right page and not [2mc+01] (wrong).
➢For more details as to why this message is extremely important, see the section the 2 rules of minicalendar dayvalues section of the GridTemplate design guidelines topic.
This message is a special case of message 187540 and is only issued when message 187540 is not applicable (that is to say, the DayValues of all the minicalendars within each page are the same, but differ from on facing page to another).
Solution
Review rule 2 of the section the 2 rules of minicalendar dayvalues of the GridTemplate design guidelines topic, and decide which DayValue to use for all the minicalendars of your spread.
