Changing the Numeric Field value from six decimals to two decimals in attribute table does not show changes for the labels displayed in ArcGIS Pro 2.1.2.
The Arcade language parser is being used in this case. When using Arcade, field formatting on the layer will not be brought over to the labels. Arcade formatting methods must be used. Please see this help topic:
