You're passing a node set consisting of all the LAST_UPDATE elements
to the rioport:formatDate() extension function. I have no idea how
that extension function works, but I suspect that it takes the first
node from that node set and returns a string, rather than formatting
all of them and returning a node set.

I think what you probably want is:

                           rioport:formatDate(LAST_UPDATE)) &lt; 0]]

This applies templates to:

  the PRODUCT elements that are children of the PRODUCT_LIST element
       that is a child of the current node
    where there is a TRACK element that is a child of the
          PRODUCT_DETAILS element that is a child of the PRODUCT element
       for which the result of comparing the $trimDate to the
         formatted value of the LAST_UPDATE child of the TRACK element
         is less than 0

I hope that helps,
