That is already a conversion from something with Hard returns. Every line is a paragraph.
Can you see the real Paragraph break?
Use Sigil and some REGEX to remove the excess

</span> </p>
<p class="P-P"><span class="S-T">

but leaving the real Paragraph end.

You could also try setting the Unwrap factor slightly lower.
