Ensure that you're using the same login with both Adobe Analytics and Adobe Launch. Furthermore, ensure that you're working in the same organisation with both Adobe Analytics and Adobe Launch.
In your Analytics extension in Adobe Launch, if you did not configure the report suite through the available dropdown, then you will also not be able to see any of your configured eVars (and props and success events) in the Set Variables action. But not to worry, you can still set your values accordingly, just ensure that you're setting them with the correct eVars (and props and success events).
