Note the enwiki comment above, appears to only occur if the student trying to register does not have a gender specified in preferences - and they are prompted to "optional" select a gender to complete enrollment - but any option leads to the failure state; if they set a gender in preference first this dialog page is not presented and the enrollment passes

mmodell changed the subtype of this task from "Task" to "Production Error".Aug 28 2019, 11:11 PM
