error in ArcGIS visualization

Hi all,

I am using the ArcGIS Visualizations in one of my dashboards.

I have the zip code for 4.200 clients in Brazil. When I set the zipcode variable to the location, i get an error (bottom left corner of the visualizations) that says that the map wasn´t able to locate 81 elements. I am very happy with the result taking in account that it was able to locate 98% of the zip codes I provided. However, I was wondering if there is a way for me to figure out which clients had the error in order for me to fix it..  I cant find anywhere to click where it would provide me that answer.

Can anyone help, please?

Thanks in advance
