It may happen that your custom Portfolio categories and products, assigned to them do not appear on the frontend, however they are under the Published status in your WordPress template.
Follow these steps to deal with the issue:
Open a necessary Portfolio/Gallery page to edit and check its page template type under the Page attributes on the right.
For example, it is Filter folio 3 cols page template type. Then navigate to Cherry Options > Portfolio.
Increase the amount of portfolio posts to be displayed on Portfolio 3 columns items amount page and save changes.
