Copying by/via metabox, custom post types etc.

1) Copying single items via/by metabox is not working. Although I have created and chosen a group of sites I want to copy to I get a pop-up box telling me to choose a group.

I have tried to copy regular posts and events in The Events Calendar version: 3.4.1 by Modern Tribe Inc.

2) Copying Custom Post Type (products, events...) by/via Network admin gives me the msg "You must select a post type" after having selected the site to copy from and clicking "Next step"

The Multisite Content Copier plugin is network acivated.

Copying regular posts by/via Network admin works.

Thanks for help!
