aeiou-Namedays are defined in Namedays Options but the DiaryGridLine does not use them
Source : DiaryGridline.
Cause : One of the Namedays in the Namedays Options has a Holidays Sets specified for it to override the set selected in Namedays property of the International ScriptLine. However Q++ could not find any GridTemplate, or DiaryGridLine property which referred to that Namedays List (ie. a-Namedays, e-Namedays, ...).
Consequences : You have set Holidays Sets for Namedays that will never be used.
•Change the Holidays Sets used : Opens the corresponding Holidays List property editor, so you can remove references to any Holidays Sets.
•If, on the other hand, you have forgotten to refer to Saints in Macros, then go in the appropriate DiaryGridLine and modify that property.
