Arcgis Pro 3.2.2
I have the feature weight of the green lines below wet to 1000 for interior and exterior.
The label ( separate feature) is set to best position and top left zone as 2 rank. maximum offset is 1000 map units (trying to let it move)
Maplex label engine is on.
Thought it may be the balloon that is not considered in the label placement but the text is overlapping the feature with a weight of 1000.
Would anticipate for the "16-20" label it would move to the top left zone and cant figure out why it so not.
