Hi
Just tested your file under LO 4.0.5.1 (the Release Candidate for the next
version of the 4.0 branch) and it worked as expected (i.e. the deleted lines
were moved to the bottom and show PAGADO)
I think some of your explanation was lost in translation. There is a very
active help mailing list in Spanish here

Hope this helps!
