Printing with higher print quality repeats labels

[SydorukMariya]

Hi, I have an issue with labels when printing my map on AGOL.

Whenever I use a printing tool (either custom or default) on AGOL to print this particular web map in Map Viewer or Experience Builder and set higher print quality (e.g. 300 DPI) it repeats labels of some random polygons.  The labels settings were set in ArcGIS Pro before publishing the map image layer. There is nothing in my data that would justify this behaviour. The duplicate labels also never appear when just browsing the map. 

I'm attaching pictures of the same part of the map, when printed with 300 DPI and in worse print quality.

Any idea what could cause this?

I would look into duplicate values in your dataset to make sure that there's not two features where the labels are stacked.

There are not, each value of the attribute used for the labels is there only once.

Did you find a solution to this issue? I am having the same problem.  The map prints with on label per polygon at 96dpi but they are duplicated when I increase the resolution to 300dpi.
