[Rivet] rivet-mkhtml only taking certain changes from .plot file

Hi Rivet Experts, 

Its me again :) 

Im currently having another pretty weird error (I checked with another friend here and we coudnt solve it) with changes to a .plot file and mkhtml command. 
So i have several plots in my analysis and for two particular histograms, any changes i make in the .plot file, only a part of that gets carried over to the actual plot. 

Let me give you an example: very simple plot for the Z Mass 
this is what i have in my .plot file: 
# BEGIN PLOT /JEWEL_ZpJet/*
XTwosidedTicks=1
YTwosidedTicks=1
RatioPlotYMin=0
RatioPlotYMax=2
# END PLOT

# BEGIN PLOT /JEWEL_ZpJet/Z_mass
Title=JEWEL+PYTHIA PbPb $\sqrt{s}=2.76$ TeV, Z+Jets
XLabel=Z mass [GeV/$c^2$]
YLabel=$\frac{d^2\sigma}{dm\ d\eta}$ [pb/GeV/$c^2$]
LogY=1
CustomLegend=Z$\rightarrow\mu^{+}\mu^{-}$
# END PLOT

Now, I build-plugin, run it over some sample mc events, and do mkhtml and this is what i see in my Z_mass.dat file:
# BEGIN PLOT
XTwosidedTicks=1
YTwosidedTicks=1
Title=JEWEL Z $\rightarrow \mu^{-} \mu^{+}$
LogY=0
RatioPlotYMax=2
CustomLegend=Z$\rightarrow\mu^{+}\mu^{-}$
LegendOnly=//afs/cern.ch/work/r/rkunnawa/JEWEL/ANALYSIS/test_zpjet.yoda/JEWEL_ZpJet/Z_mass
XLabel=Z mass $[GeV/c^2]$
YLabel=$d\sigma$
DrawOnly=//afs/cern.ch/work/r/rkunnawa/JEWEL/ANALYSIS/test_zpjet.yoda/JEWEL_ZpJet/Z_mass
Legend=1
RatioPlotYMin=0
# END PLOT

# BEGIN HISTO1D //afs/cern.ch/work/r/rkunnawa/JEWEL/ANALYSIS/test_zpjet.yoda/JEWEL_ZpJet/Z_mass
ErrorBars=1
LineColor=red
... 


The histogram title and y axis label are different! they are what i have before. But the new custom legend i put in is taken!! 
this is quite bizarre when the other plots in the same analysis have no such problems. 

Cheers
Raghav
