system user is enable to read from Editionable view

hello all,

I have been working so long to figure out the issue here.
we have editionable view abc under xyz schema.
when I connected as xyz user and query 
select count(*) from xyz.abc;

 COUNT(*)

----------

        37

however, When I connected as sys or system user and query the same select statement I get 0 rows.
select count(*) from xyz.abc;

  COUNT(*)

----------

         0

I have tried to create a public synonym for the editionable view but still doesn't work.

can anyone help me on
