Conflict with link share – post to page as comments, not as page manager

Hello, I’m having trouble sharing my posts/pages to my facebook business page as the posts don`t show as public because it says the page who posted it was the app I named “comments”.

What should I do? it`s a big problem since they are not visible to other people. my website is https://www.mundolinguas.com.br

thanks!
