Different plots with the same code?

[dr-jojo]

I ran a model with the c5.0 but when I plot it I get different results each time. Specifically the barplot on the terminal nodes change slightly. I attached a picture as an example. I may not be understanding something, but help would be appreciated. Thanks

sex.mod2.c5= C5.0(x=offenders.train.imp[c(-1, -2, -3, -4, -6, -7, -15, -50, -51)],
y=offenders.train.imp$Sex,
control = C5.0Control(winnow = TRUE,
minCases = 10,
noGlobalPruning = FALSE,
seed = sample.int(12345, size = 1) - 1L))

plot(sex.mod2.c5)
