Confidence interval and p-value labels have different height and fontsize

[LSYS]

The "Confidence interval" ylabel and the "P-value" headers have different height and fontsize:

import pandas as pd
import forestplot as fp

df = fp.load_data("sleep")

fp.forestplot(df, # the dataframe with results data
 estimate="r", # col containing estimated effect size 
 ll="ll", hl="hl", # columns containing conf. int. lower and higher limits
 varlabel="label", # column containing variable label
 pval="p-val", # Column of p-value to be reported on right
 ylabel="Confidence interval", # ylabel to print
 )
