'Angular Coordinate Dimension' is only showing degree symbol at zero.
Solution
When 'Units->Angular->Round-off' is 1, which is the default, the 'Leading' and 'Trailing' zeros properties are ignored. This will display the zero value for degrees. But if you have 'Units->Angular->Round-off', such as .1234 with 'Leading' and 'Trailing' zeros unchecked, it will result in a blank value at zero degrees. Hence, you will need to check those properties to display zero degrees.
