W3Validator notices about unnecessary trailing slashes

The generated meta-Tags from the OG Plugin contain an unnecessary trailing slash /, as discovered by the W3Validator for my rendered Site:

Info: Trailing slash on void elements has no effect and interacts badly with unquoted attribute values.

<meta property="og:image" … />

The causing lines of code within the OG Plugin can be found here:

og/includes/iworks/class-iworks-opengraph.php

924: printf(
925: '<link rel="image_src" href="%s" />%s',

938: printf(
939: '<meta name="msapplication-TileImage" content="%s" />%s',

1087: sprintf(
1088: '<meta property="%s" %s />%s',

1136: sprintf(
1137: '<meta %s="%s" content="%s" />%s',
