It is a paid for theme (Apollo Modern Magazine Newspaper Template), according to the developer, there are javascript conflict between theme’s script and plugin’s script.
and yes the slider used on the home page is puling the posts of one English category. as well as the recent posts are pulled from another category, both categories synced with French posts.
I am going to go through the documentation if I can find a work around solution.
However, if you have any ideas, Please let me know It will be appreciated.
