"Cloner" plugin does not clone pages in a multisite


I am setting up a multisite network which contains a few subsites. I want to be able to clone any of the subsites at any given moment to a new subsite. When I use the plugin "Cloner", the subsite is cloned (to a new subsite), but the pages are not cloned. Everything else seems to be cloned correctly.

How is this possible? In the Cloner settings, every content type to be copied is checked (including Pages).

The subsites that I want to clone are based on the Bryte theme, which is a multipurpose theme. It contains seven types of websites. Each subsite is using a different type of website from that theme.
