Wow! thanks epickenyan for sharing! now works fine !

Same problem here, Yoast said this:

We checked your site and found that the Yoast plugin is outputting the correct OpenGraph tags that Google+ uses to create the snippet in your site. See attached image source.png.
However, we found some additional microdata tags lower down in the source, that seem to be overwriting the information in the OpenGraph tags. See attachment microdata.png

Sometimes strange behavior may be caused by a plugin or theme conflict. The fastest way to rule out conflicts is to deactivate all non-Yoast plugins and switch to a standard theme like Twenty Seventeen. If this resolves the issue, you have a conflict and should activate one plugin at a time until you locate the conflict. Finally, after all plugins are active, switch to your theme. This will narrow down the conflict to a specific plugin or a theme conflict.

I did many test like Yoast recommend, and the Google+ sharing on posts bug, continue when activate Newspaper theme.
