There are two problems which will cause this issue.

1. Partially created Activity in your account.Steps to delete partially created activities:

   In MyHarmony Desktop Software:

   • Launch MyHarmony
   • Click on “Activities” tab from Remote Gallery, you will find the Activities with exclamation icon (those are partially created Activities), delete it and create/rename Activity with the same name

   For deleting Activities:

   • Click on the specific Activity to be deleted
   • Click “Delete your Activity” device will be deleted.

2. Harmony will not allow duplication of device name in Activities.

   If you try to name an Activity similar to the device name which is in your account you will get an error stating “This name is already used in your account - please use another name”

   Example:

   If you have a device name "Fire TV" in your account, it will not allow you to name an Activity as "Fire TV", instead you can create it as "FireTV" without space.
