disabled slack enhancing but still showing up

I don’t know who on your team thought it would be a good idea to expose the admin email address in the source code through the twitter meta. That being said, I turned off the Titles/Meta > Posts > Slack option, but the twitter meta is still showing up.
<meta name=”twitter:label1″ content=”Written by” />
<meta name=”twitter:data1″ content=”a***@m********************” />
<meta name=”twitter:label2″ content=”Time to read” />
<meta name=”twitter:data2″ content=”1 minute” />

How do I hide this data?
