When signing up for your Giving Day, you also signed up for GiveGab! This means, you have both a GiveGab profile and a Giving Day profile.
If you made your changes by clicking the "Edit Profile" link on the left-hand side of your Admin Dashboard, your changes will only be reflected on your GiveGab profile, and not your Giving Day profile:
Only changes made from your Giving Day dashboard will be reflected on your Giving Day profile.
To navigate to your Giving Day Dashboard
From the Overview Tab of your Admin Dashboard, scroll until you can see the "Giving Day" box. Click on the "Giving Days" box then follow the prompt for your Giving Day to access your Giving Day Dashboard and edit your profile.
