How do I plot multiple caterpillar plots in one graph in ggplot?

Question

So I have successfully plotted these graphs individually, now I want to create a plot that has all three categories in one graph with same scales but different colors. Here is my dataset after combining three individual datasets (df_psi, df_gamma and df_eps)

structure(list(label = c("LC5", "LC6", "LC8", "LC9", "LC10", 
"LC11", "LC12", "LC13-17", "bio4", "bio5", "bio12", "bio14", 
"bio15", "NDVI" "bio5", "bio12", "bio14", 
"bio15", "NDVI", "LC5^2", "LC6^2", "LC8^2", "LC9^2", "LC10^2", 
"LC11^2", "LC12^2", "LC13-17^2", "bio4^2", "bio5^20", "bio12^2", 
"bio14^2", "bio15^2","LC9^2", "LC10^2", 
"LC11^2", "LC12^2", "LC13-17^2", "bio4^2", "bio5^20", "bio12^2", 
"bio14^2", "bio15^2", "NDVI^2"), mean = c(-0.02, 0.08, 0.06, 
-0.37, 0.19, 0.17, 0.46, -0.45, -0.1, 0.47, 0.2, -0.51, -0.11, 
0, 0.35, -0.08, 0.22, -0.15, 0.38, 0.39, 
0.24, -0.02, 0.05, 0.03, -0.05, 0.01, -0.07, -0.94, 0.31, -0.06, 
-0.31, 0.05, 0.52,-0.27, -1.22, -0.91
), lower = c(-1.01, -0.86, -0.68, -1.41, -0.4, -0.63, -0.22, 
-1.6, -0.94, -0.33, -0.35, -1.51, -0.89, -0.77, -0.1, -0.03, 
-0.29, -0.92, -0.63, -0.05, -0.42, -0.75, -1.14, -1.05, -0.3, 
-0.64, -0.24, -0.04, -0.89, -1.25, -1.33, -0.87, -0.79, -0.93, 
-0.42, -1.44, -0.45, -0.38, -1.41, -0.66, -0.39, -1.17, -0.1, 
-0.01, -0.7, -0.44, -0.25, -0.6, -0.61, 
-0.56, -0.79, -2.99, -1.82), upper = c(0.96, 1.1, 0.87, 0.42, 
1.03, 1.23, 1.53, 0.31, 0.53, 1.86, 1, 0.14, 0.53, 0.78, 1.51, 
1.86, 0.9, 0.07, 0.47, 1.49, 0.42, 0.06, 0.4, 0.51, 0.46, 0.21, 
0.88, 1.5, 1.47, 1.22, 1.05, 0.83, 1.34, 1.36, 2.19, 0.36, 0.86, 
2.54, 0.13, 0.42, 0.37, 0.16, 1.29, 0.8, 1.32, 0.49, 
0.04, 0.17, 0.02, 0.78, 0.3, -0.06, 0.32, 0.46, 0.08, 0.97, 0.22, 
0.1, -0.11, -0.14), Type = c("psi", "psi", "psi", "psi", "psi", 
"psi", "psi", "gamma", "gamma", "gamma", 
"gamma", "gamma", "gamma", "gamma", "gamma", "gamma", "gamma", 
"gamma", "gamma", "gamma", "gamma", "gamma", "gamma", "gamma", 
"gamma", "gamma", "gamma", "gamma", "gamma", "gamma", "gamma", 
"gamma", "gamma", "gamma", "gamma", "eps", "eps", "eps", "eps", 
"eps", "eps")), row.names = c(NA, 
-84L), class = "data.frame")

I am using similar code to plot individual graphs and now trying to implement it for this new graph with three categories

all_plots  <- ggplot(data=all_posterior, aes(x=label, 
                                             y=mean, 
                                             ymin=lower, 
                                             ymax=upper, 
                                             color = Type)) +
  #geom_pointrange(col = Type) + 
  scale_y_continuous(breaks = seq(-6, 6, 2)) + 
  coord_cartesian(ylim = c(-6, 6)) + 
  theme_bw()  + # use a white background
  ggtitle("CC") +
  theme(axis.text.x = element_text(angle = 90, vjust = 1, hjust=1, size = 20),
        axis.text.y = element_text(size = 20),
        axis.title.x = element_blank(),
        axis.title.y = element_blank(),
        plot.title = element_text(hjust = 1, size = 20)
  )  

The code is running fine and not giving any errors but the graph windows comes out blank.
