View Vertical Annotation Cardinal Point leader length not changing

Power InRoads V8i (SELECTseries 4) 08.11.09.04

In Geometry --> View Geometry --> Vertical Annotation

I am trying to edit the cardinal point leader length, and it seems to be stuck at an arbitrary minimum of 300.

Changing 'Segment 1' to a value of more than 300, increases the leader length to that amount.

'Segment 1' values of less than 300 result in no change. (stuck at 300 length)

'Segment 2' value changes result in that leader length value change. 

I am in a 1:1 drawing with no annotations or scales used.
