Hello @restyumali-sl

Sorry! it’s not a problem. By default theme enables slogan and slider in blog page as well front page.
You can disable it in blog page via creating a new page with blog template.

Just create a new page with any name and at the right side of the page editor there you can see Page Attributes choose any template (Blog image large, Blog image medium and Blog full content) and publish the page. Now this page shows blog.
then go to Setting -> Reading under Your homepage displays option choose A static page option and select the page that you want to show in your Homepage and choose the page that you have just created on Post Page and save it.
Now just open that page and you will not see slogan and slider in your blog page.

Thank you!
