I have created a plan and calculated grades using the very useful grade tool. I have used the grade tool in viewport annotation. However, every time I move the viewport on the page the data with the arrow (percentage grade/fall) on the viewport disappears. The data is still there and correct but to get the grade to show (which is what I want) I have to go into the viewport, individually select each grade, then press return for the information to reappear. I can appreciate if I moved the viewport on the design layer or the viewport crop, the grade tool would have to reassess all the information (which it does if I do this), but why is this information missing when I just move the viewport. It is a huge waste of time do reset these each time.
The first image is what it looks like, the second what it should like and what it does look like after I individually select each grade to reset.
Thanks for advice, grade calculation is painful enough as it is, without this added headache!
