Hello - The basemap tool in the Experience Builder map tools now shows custom basemaps in the basemap gallery twice when a custom basemap is used as the webmaps basemap.
When a custom basemap is not used as the webmap basemap, for example the Streets or Topo, this is not an issue.
To see what I mean you will see the "Sarasota County Local (Vector)" basemap twice:
https://experience.arcgis.com/experience/36f63bf761e4483b9e89120efe8ed860
The webmaps in this app use a custom localize basemap with some vector tile layers. When the user opens the basemap tool, this custom local basemap appears twice.
I am not seeing my custom local basemaps twice in my AGOL custom basemap group, the webmap count making up the basemaps show as expected, i.e there are no duplicate webmaps. The AGOL custom basemap group does however participate in a distributed collaboration, where I send the custom vector tile layers to the group by reference from our guest Enterprise Portal.
Thanks-
@Jianxia
