Nonzero Status for pp > WWW at NLO

Hi Folks,

I am trying to simulate pp > www + madspin at NLO(+PS) but am getting yelled at by MINT for having a nonzero width. The thing is, I have no problem for tt or ttW and setting the W,Z,h, and t widths to zero in the param_card does not fix the issue. Details are below. Any suggestions on how to deal with this?

Thanks!

Best,
Richard

1. My version is:
version = 2.5.5
date = 2017-05-26

2. The proc card contains the following:
import model loop_sm
define p = g u c d s u~ c~ d~ s~
define ww = w+ w-
generate p p > ww ww ww [QCD]
output SM_pp_WWW_NLO

3. The run and param cards are the default files.

4. After launching, I get the following:
MG5_aMC>launch SM_pp_WWW_NLO
INFO: Cleaning previous results

5. Running "ajob1 8 F 0 0" gives me the following log_MINT0.txt output in P0_udx_wpwpwm/GF8:
