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-
Weird...this is what I see, and I do not find the duplicate ones
That is strange @TonghuiMing - your screen shot does not show the custom vector tile layers making up the basemap - it is only showing the light gray base. The screenshot from @Ke_Xu is showing what I have been seeing - and am seeing this morning - 2 basemaps that are only being duplicated in the basemap selector tool.
This local basemap at:
https://sarco.maps.arcgis.com/home/item.html?id=32f5e05a349d4dc98bc2ce90b34e4f04
consists of the following:
Light Gray Reference - US - Copy

Local Detail labeling vector tile layer:

Local Base vector tile layer:

Light Gray Canvas Base:
https://basemaps.arcgis.com/arcgis/rest/services/World_Basemap_v2/VectorTileServer
Both of the basemaps.arcgis.com layers will not update their sharing, so this is probably all related to the Online update.
Also @Ke_Xu and @TonghuiMing - If you go to my experience here:
https://experience.arcgis.com/experience/48741ab2a7b24c0fb5f360d0f40824d5/page/Home
All 3 of these maps use the Living Atlas world topo as the webmaps' default publication basemap, and you can see that there is no issue of the 'Local' maps being 'duplicated' in the experience basemap map tool.
Thanks
