    Hi Ryan,

     

    That sounds like it might be a bug (GE-4896) that had a fix implemented in v4.9.1 - are you on an earlier version than that?

     

    We tend to see this issue when changes are applied to group layers from ArcGIS Server. 

     

    I'd suggest trying the following:
    • Open the site in Manager, and if there is a yellow triangle icon in the top left corner, click on it.
    • Accept any prompts to re-map or re-add the layers from group layers
    • Save the site
    • Close the site
    • Open the site again
    • Try and make the layer list changes again. You may also want to try editing the affected map services first, and confirm that the layers you're working with are added in the "Add/remove layers" tab.
    If those steps don't help, try contacting your support provider, and they may be able to support you through the process.

     

    Thanks!

     

    Stephanie
