Hi Mohammed,
Yes as above by NOT setting the blog page in Settings> Reading.

In the documentation you do warn about this:
“NOTE: DO NOT set the posts page in Settings > Reading, as this will force your page to show the archive layout, and not follow your created page.”

It may help to add that warning in the Blog asset of SPB when you choose Social Integration perhaps that text could be added to prevent other having same issue.
Cheers,
Tom
