Class (para-Normal-Local-13) is your regular paragraph text and its justified for all the <p> tags except the first paragraph which uses "para-Normal-Local-7" tag for that.
A <span> class (char-Normal-Local-75) effects all of the other above mentioned <p> tags, and its NOT effecting nor reversing any of the 'justify' settings.
Neither the inline CSS nor the external linked CSS indicate that the justify on <p> tags is being negated.
When I looked at it on Firefox Developer screen it renders as "justify".
There are three CSS elements set with 'text-align:right' -- but none of those are being used in that HTML doc page.
If you add a sentence or two of "Ipsum Loren" test text you'll see the first paragraph's justify effect more readily.
Summation: You have "justify" correctly set in <p>.
