Have you first tried to deactivate all plugins and see if the meta property in question disappears?
If so, then reactivate one by one to find which plugin is responsible.
If not, then @weaver would have to confirm if it is indeed the theme generating the meta property=”og:image”….
If so and given support has ended on weaver II pro (now replaced by weaver Xtreme), the only potential solution would be if a child theme could modify that. again something that only weaver could confirm.
