I see a special Post type called Styled Portfolios, but I’m not exactly sure what it’s used for and the page layout doesn’t seem to work correctly.
Are you creating a Page or Post and inserting a WordPress Gallery then styling it from there? Can you please provide a better instruction page and/or let me know the page/post type you are using and how created both pages?
Are you sure that you have created post under styled portfolios and place the short code on page editor switching it to text mode. ?
if you want to separate your portfolio, you have to write custom query. You can see the WP_Query document here
You can create new short code placing on child theme , and use this on page editor to show up the list of portfolios. You can take reference of ‘style_portfolio’ short code while creating new one. ‘style_portfolio’ is declared on /theme folder/shortcodes/portfolio_shortcodes.php
Note: Please start customizing the theme only if you are technically sound on WordPress , otherwise you may face php error.On this circumstance we recommend you to take help from a WordPress developer.
Also we reqest you to provide url of page where you have placed shortcodes so we can provide you the appropriate solution. The one you have send us leads to the page not found .
