Hello,
I’m afraid that there is no way to do this without additional customization. You have chosen slider for the blog page instead of the heading http://prntscr.com/ftx9cy it means that all the posts categories will show this slider because they inherit Blog template by default. Category description is part of the category content, it’s not page heading. And post category does not have the option to show slider instead of the category heading.
You may contact WPKraken team to get help with additional customization.
Regards
