Getting started tutorial - missing actors

Hello,

I am following the Getting Started tutorial and I am configuring who can do what

At the following step:

1. Select the Customer lane

2. Go to General Actors

3. Click on Set…​ next to actor filter

4. From the list, select Initiator

I have only one option in "Actor filter definition" list instead of multiple options like in the tutorial screenshot.

I reviewed the previous steps but still face the issue.

Any idea how I should proceed?

Thanks!
