Can't hide holidays on front end

When you select “Check this if you wish to hide this holiday on frontend” it doesn’t hide the holiday. I found the below in the database when I attempted to hide the “4th of July’.

{“name”:”4th of July”,”start”:1435968000,”end”:1435968000,”desc”:””,”desc_disable”:”o”},{“name”:”Thanksgiving”,”start”:1448496000,”end”:1448496000,”desc”:””,”desc_disable”:”n”},
