Eta cuts in run_card not respected

Hello MG team :)

I am using MG5_aMC_v3_4_0 to generate:

generate u u~ > z b b~
add process u~ u > z b b~

I want to generate it in a certain pT range and as central as possible. Here are my cuts:

#*********************************************************************
# Minimum and maximum pt's (for max, -1 means no cut) *
#*********************************************************************
  0.0 = ptj ! minimum pt for the jets
  -1.0 = ptjmax ! maximum pt for the jets
  {'23': 400.0} = pt_min_pdg ! pt cut for other particles (use pdg code). Applied on particle and anti-particle
  {'23': 600.0} = pt_max_pdg ! pt cut for other particles (syntax e.g. {6: 100, 25: 50})
#
# For display option for energy cut in the partonic center of mass frame type 'update ecut'
#
#*********************************************************************
# Maximum and minimum absolute rapidity (for max, -1 means no cut) *
#*********************************************************************
  0.05 = etaj ! max rap for the jets
  {'23': 0.0} = eta_min_pdg ! rap cut for other particles (use pdg code). Applied on particle and anti-particle
  {'23': 0.05} = eta_max_pdg ! rap cut for other particles (syntax e.g. {6: 2.5, 23: 5})

Looking at the LHE files and the outgoing parton, I find that the pT cuts are properly applied, but the parton has eta all the way up to ~2.5.

Is there a reason why the eta cuts are not respected?

Thanks
