Hi
Your menu item aoren-community is using the landing template layout , in this layout there is no positions available for your ja acm modules published in acm-features position, remember that this position is a virtual position created by another ja acm module ( that i created for you) and name is features, in this module that act as a container you can define the position where shows your 3 ja acm modules and it is published in section position , so you will need of a layout with section position or add this position to the landing layout
Hope was clear enough
