I have 10 feature service layers on a web map in arcgis.com for organizations beta. When I build a Silverlight application using this viewer and link it to that web map the layers list shows one layer 9 times (see screenshot). I'm not sure what to make of this or how to fix it. I've tried publishing the app to see if it would fix it, but I still have the issue. I've even deleted the app and started over (again using the web map as a starting point). Any ideas?
