Identifying dynamic data masking

Amelia got back to us and said she's seeing Xs instead of the name in the organizationformalname field of the idahositeid table. Here is the snippet she sent.

pk_siteid fk_monitoringlocation organization_id organizationformalname
102 4964 1119USBR_WQX-MIN761 XXXXXXXXXXXXXXXXXXXXXX

Yet you can see all the values in that field and they normal values.

pk_siteid fk_monitoringlocation organization_id organizationformalname
102 4964 1119USBR_WQX-MIN761 Bureau of Reclamation

What is likely happening to Amelia's query?
