Not work on my Freak theme FIX Please :)

Hello your plugin is great, the problem I have is that I removed the Post date but the date still appears in the snippet in search engines Google .

I left it for 2 weeks and the date is still indexed . Could you fix it please?

in the post date does not appear: https://elpoderdelandroideverde.com/5-dias-de-uso-xiaomi-redmi-note-2-prime/

but the date is always indexed in google: https://www.google.es/webhp?sourceid=chrome-instant&ion=1&espv=2&ie=UTF-8#q=5%20dias%20de%20uso%20xiaomi%20redmi%20note%202

This is my THEME https://rohitink.com/2015/04/26/freak-multipurpose-theme/

Thanks !!
