Problem with google not seeing my Item

Hello everyone,


I'm concerned with my Schema ("@type":"Periodical" or 
"@type":"PeriodicalIssue").

When I use the Schema.org tool ( https://validator.schema.org ) its 
seems to see my Json but if I use google tool, it do not see anything?


What am I doing wrong?



Thank you
