ARM Report Manager parameter query not passing parameters

I intended to use a list of ARM Profiles as a parameter to another query. I created the SQL below, which generates the desired output in SQL Developer, but when saved as a parameter query, nothing comes up. Even when I edit report, the parameter value list is still empty. The parameter type is defined as a query.

SELECT ProfileEO.RECONCILIATION_ACCOUNT_ID

FROM ARM_RECONCILIATIONS ProfileEO

WHERE (ProfileEO.PERIOD_ID IS NULL)
