Theresa,

This is not a problem, but you must have 2 pqact entries going to
different files.

I just noticed that both output files from the pqact entries  have
the same name. I believe that's the problem because one cannot have 2
pipes going to one file and get consistent results. One doesn't have to do
any special things, just 2 pqact entries going to different output
files should work fine.
