This issue was identified as a bug and resolved in the February 2017 release of the RELO plugin and web services. Please update to the latest plugin and web service version to resolve this issue.

NOTE: The types of data downloaded into Raiser's Edge may depend
 on what gateway the transaction is processed. For example, Cardholder Name will not download for PayPal transactions downloaded as “XCheckout” transactions. The XCheckout functionality allows donors to connect directly to their third-party payment account (such as, PayPal) to make their donation. Paypal payments are managed through your organization's PayPal account, meaning they get basic information on the donor in LO but the actual donation transaction is managed from PayPal not your Luminate merchant account.
