Scale-based sizing for label not working in ArcGIS Online (duplicate labels)

Question

Hi All,

I have been having duplicate label issue when using scale-based sizing for label in ArcGIS Online (I found no issue when viewing the web map in ArcGIS Pro).

I have a feature service, called Sections in the web map, which is basically displaying a boundary of land parcels group. I created two label classes to display the section numbers at a different zoom levels, as below:

* 1st label class (APPROVED) is set to display the labels with the scale range of 0-4505.
* 2nd label class (APPROVED_LRG) is set to display the labels with the scale range of 4506-36111

However, the labels from both classes appear when I zoom in to the 4505 scale, result in duplicates. As can be seen from the screen shots:

Has anyone encountered similar issue or found any workaround to deal with such issue?

Thank you.

Hi Russ, I was wondering if there was any other solution for this issue? We are using a VertiGIS web app and in the application users can enter any specific zoom scale and that will cause a drop in labelling when we are using the workaround (bumped around the max/min scale) if they happen to enter that in-between scale. Thank you.

Thanks, I can see the issue and looking into it. As a work around I bumped the max scale for the SML class to 4700 and that removed the issue and I couldnt spot a drop in labeling when viewing it through a web app and changing scale.

Hi @RussRoberts, thanks so much for looking into this.

Here is the link to the public web map. The layers of interest's scale settings have been set up to test the duplicate labels issue (layers: ACTGOV Playground Assets and Sections).

Thank you.
