PHYLIP Consense tree not most parsimonious?

Hi phylogeny constructors,
In constructing molecular phylogenies using the PHYLIP package,
I encountered something which puzzles me.
I wanted a maximum parsimony tree with bootstrap values from my
protein data set, so I ran the programs Seqboot, Protpars and
Consense, using the output from the earlier as input for the
However, when I ran the resulting tree and some other trees I
made up myself through Protpars again, using the User Tree option,
I found that one of my own trees was one step shorter than the
consense, bootstrapped, tree.
Is there a rationale for this? Isn't Seqboot-Protpars-Consense
the way to find the most parsimonious tree, with bootstrap values
