Hi Rob,
I know you're new to workflows so let me assure you that there is no magic here, things are not as complicated as they might seem to be at the moment. Container elements do not just appear at runtime, they have to be defined within the workflow template.
Your screenshot above where you say you can see the container element at the top level but not at the "task" level - this mean that the container element is defined at the workflow level and not in the step you are looking at.
Open up the workflow in SWDD and look at the workflow-level container. You should be able to find CR_CREATOR_NAME there. As I said before, it does not help that you have given a different container element (..._WITH_US) the same name - please change that! Workflow shows different names (short names, long names, technical names) in different views and it can lead to confusion.
regards
Rick Bakker
