Description
The coordinate system of the parent component (for example, neatlines/ticks/segments/endpoints) of the annotation component changed from a geographic coordinate system to a projected coordinate system or vice versa. The annotation style set in the grid template is no longer valid.
Solution
Use the Grids and Graticules Designer window in ArcGIS Production Mapping to update the annotation style in the grid template XML to use a style valid for the coordinate system used by the parent component.
