Hello @posicionartemd,
I am Elvina from team Brainstorm Force, the makers of this plugin.
I am sorry to hear that the plugin isn’t working for you.
If you are using the All In One Schema Rich Snippets plugin, it adds the schema in MicroData format, which is visible in the front end. This plugin was built way back when MicroData was the only technology used and we had to follow Google guidelines to make it work.
We understand that you don’t like the content displayed on your page/post. However, as per Google, it is recommended that MicroData should be visible to the user.
If you still do not want your schema markup to affect your frontend design, you can use Schema Pro – our advanced Schema markup plugin built with the latest JSON- LD technology, which does not require a content box to be displayed on the frontend.
Note- The free plugins, i.e., the All In One Schema Rich Snippets plugin, and the Schema Pro plugin, are different.
Let me know if you have a query about the same.
