I have an existing Cached service with 10 scales. I would like to add a 11th without completely setting up the service. I'm working in Enterprise 10.8.1 and ArcMap 10.8.1. Within ArcMap I ran the tool Manage Map Server Cache Scales and it said it was successful. However when I go to ArcGIS Manager or the Service Directory I don't see that new scale and when I try to manage the scales through ArcCatalog to run it, I don't see the new scale there either.
