PROBLEM:
The scale in a titleblock says 'As Indicated' even though there is only one view on the sheet, or all views have the same scale.
CAUSE:
There is a Legend on the sheet that is a different scale.
SOLUTION 1:
Change the scale of the Legend.
If the Legend appears on sheets with different scales make a separate legend for each scale.
SOLUTION 2:
Create a Generic Annotation family containing the information in the legend and use that instead.
