ora-01720 in Oracle 12c when creating a view that includes a select from sys.dual

I have this create view statement that is failing with ORA-01720: grant option does not exist for 'SYS.DUAL' on line 7

create or replace view v_decisions

(Sort_No, Name, Abbreviation, Include_In_EM, WPSetup_ID, Include_In_MBP, Web_Name )

as

select Sort_No, Name, Abbreviation, Include_In_EM, WPSetup_ID, Include_In_MBP, Web_Name

from decision

union

select -2, 'Inquiry', 'INQ', 'N', null, 'N', null from dual

union

select -1, 'Applicant', 'APP', 'N', null, 'N', null from dual

;

The user was created by the sys user as sysdba and given the select on sys.dual with this statement.
