Workaround is to enumerate the fields and update them separately.
            foreach (var field in this.radRichTextBox.Document.EnumerateChildrenOfType<FieldRangeStart>())
            {
                this.radRichTextBox.UpdateField(field);
            }
		Hi, The issue is fixed and will be live with our next Q2 2015 release. Best Regards, Aylin, The Telerik Team
