I emailed Barclaycard and they responded that they are aware (as is American) that this is a problem and they opened a case for me. It sounds like it could take a while to resolve. They also indicated that it could impact my earning of EQD in 2018 for the calendar year - however, I assume that will be corrected once the error is reversed.
I also spoke to American who said that I needed to resolve this with Barclaycard by asking them to send American instructions to treat the award as a 2017 award.
