Missing elements in Collaboration Diagram

Hi

I'm kind of new to Modelio and I really like it. However, I have encountered some problems. Trying to use the BPMN Collaboration Diagram, I find that a lot of elements is mission, atleast when I compare my elements list to the samples I found on the net.

This one for instance:


Mine look like this:


As you can see a lot of elements is missing. Why?

I've tried to search to find if I have to download a library, purchase something etc. in order to get a complete set of elements, but I could not find any information about what is the problem.

Could someone please advice on how to fix this.

Hi,

Can you post a picture of the "End Customer" BPMN Process Diagram?

[edit]
A process shown in a Collaboration diagram will look the same as in its own Process diagram.
See attached gif animation.
