HttpRequestHandler Pollution

hi i try to add meta tag using action AddMetaTag so that it appears in the social media, in this case i try using Telegram, the output is like this:

The issue is: there is pollutant in the view source of my web - "scheme=""/>. How to remove it?

In the Telegram is also show the screen name HomeScreen. So, what is the property="og:title" for?

Thank you.

<meta name="MyCompProfile" content="

<meta property="og:title" content="Title" />

<meta property="og:site_name" content="Eddy Sites"/>

<meta property="og:description" content="Description-Nasi gerobag" />

<meta property="og:image" content="https:/" />

" scheme=""/><meta name="viewport" content="width=device-width, initial-scale=1" scheme=""/>

    <meta http-equiv="Content-Type" content="text/html; charset=utf-8" />

    <meta http-equiv="Content-Script-Type" content="text/javascript" /><meta http-equiv="Content-Style-Type" content="text/css" />




I think the meta has been correct.
