There is not a true resolution to this behavior due to the restrictions imposed by Microsoft, we would simply suggest that the field names that you create for use with the GIFTS Customizer not contain any of the words reserved by SQL Server; use of these words in your Customizer field names may interfere with the proper operation of GIFTS. Please review the Microsoft Article below for a comprehensive list of reserved keywords for SQL Server 2012:

As always, if the above issue persists even when following this suggestion, please contact us with the customer support number for GIFTS listed at https://www.blackbaud.com/contact-us/ which will always have the most up to date information,
