For me iterating lists works fine.
Use a 'foreach feature' (or any loop) to iterate on your list. Save the list element to a variable, say list_element.
Now, Use 'Enter Keystrokes' feature, change the selection to 'from variable' and choose the variable 'list_element' from dropdown menu in its description.
You can also select option 'typed text' with text as ${list_element}, this works fine too.
