Hey Achamlin,
first of all, thank you for the purchase!
I will go over the issues in the same order:
1). There are two settings that regulate the number of portfolio items in grids in Kanso: a). Number of items on One-page template: Theme Options, “One-Page Website” tab, “Number of portfolio projects per page” and b). Number of items on Portfolio template (also the page you get redirected to when you click on the “See All” button from the One-Page template): Theme Options, “Portfolio Page” tab, “Portfolio items per page”. Please check that you are using the relevant option. The filters are sourced from the portfolio “types” taxonomy (“Portfolio -> Types”) – please make sure that you have at least one type set up and assigned to at least one project in the abovementioned section of the admin panel.
2). There is a special project format called “gallery” which has been designed exactly for displaying a slider-gallery of images; you can choose the format from the “Format” settings box on the right hand side of the editor screen for the respective project. You can find more information on how to set up each post and project format on pages 8-9 of the theme manual.
Sincerely,
Andrii / Satori Studio
