I'm still not able to recognize the problem. All items consist of one line. Which indentation exactly do you mean? And what in this context are the subsequent lines you mentioned.
Even if the items have more than one line. Where exactly is the problem? Perhaps you can enlighten me. I still can't figure out which indentation you mean. Seems that I get my wires crossed.
Sorry, I'm still unable to make sense of that. Are these lists supposed to appear with the width of the text body? Please give a visual example.
If you wonder why I ask all these questions you should know that there are several list parameters which determine several indentation properties of lists. So you should be more specific.
I uploaded a screenshot of the PDF in question. You can see the lines after the first in the list are still indented, while the bulk of the text (the two lines above) is not.
