You see a gift attribute displayed under the additional information section of your donation form when viewing the donation page. When you edit the donation form part, you may not see the attribute listed. When you save the donation form part the attribute may disappear from the page.
The gift attribute may have been cached on the page. If the attribute does not show in the donation form part editor, this indicates the attribute has been deleted or marked inactive in Raiser's Edge. When we save the donation form part, this will update the page and override any possibly cached information which would remove the no longer active/existing attribute.
If you would like the attribute to display on the page, you may need to add the gift attribute or update the attribute's settings in Raiser's Edge.
