Print Text and Spooled Files

I have a weird one here.

One of my tools, SPL2SPL, allows a user to copy a spooled
file.  It also allows them to change certain spooled file
attributes for the new spooled file.

Now, I have a couple users who use the Print Text paramter,
and it does not seem to change the print text on the
duplicated spooled file.

I have run this in debug 100 times, and I can see that the
print text parameter of the new spooled file HAS changed.
But when the spooled file is printed, the print text from
the original spooled file appears on the output instead of
the new Print Text.

The documentation on this field is sparse, so I'm at a loss
as to why this isn't working.

Example..

SF1 - print text = "Hi!"

Use SPL2SPL and change print text to "Bye!", creates new
spooled file SF2.

Print SF2, and "Hi!" prints as the print text.

Use SPL2SPL to copy SF2.  I run it in debug and retrieve the
spooled file attributes and the print text IS "Bye!".
Change it again to "Grape!" which makes SF3.

Print SF3, print text still is "Hi!"

Hope this makes sense.  If anyone wants to give it a whirl
to see what I mean, you're more than welcome.  I'd
appreciate any clues or help.  Thanks!  I'm pulling my hair
out on this one.
