Demo home page still showing

1. I changed home page from default demo to shop from homepage setting. But the default demo home and menus still showing upon first visit. However, after refreshing the page shop appears. I moved all home pages to the bin but it still shows. How can I can permanently change it?
2. Is there is a way to to remove slider from default demo homepage?
3. Is there a way to uninstall all demo pages and settings?

Hello,

1. Please deactivate the plugins, cache plugins and check the issue. The home page is set in the Dashboard > Settings > Reading.
2. Edit the home page, and remove the row containing the slider https://gyazo.com/e8d3d1f47d2f9b5707e1d66b999f6ed9

3. You need to delete all the pages, products, images from your site. There is no option to remove all automatically.
