GGpairs, correlation values are not aligned

问题

I am trying to create a correlation matrix using GGpairs, the scatterplots are coloured by group (reg or irreg). The correlation values plotted on the upper corner are not aligned, as you see in the image here the Cor, reg and irreg values are not aligned.

The code I use is this:

ggpairs(data=dat4,
   columns=1:5, 
   title="correlation matrix",               
   mapping= aes(colour = irregular), 
   lower = list(
   continuous = "smooth",
   combo = "facetdensity",
   mapping = aes(color = irregular)))

The data is here: replicatable data

Any suggestion? Thank you thank you!

This seems to work:

ggpairs(data=dat4,
        columns=1:5, 
        title="correlation matrix",               
        mapping= aes(colour = irregular), 
        lower = list(
          continuous = "smooth",
          combo = "facetdensity",
          mapping = aes(color = irregular)),
        upper = list(continuous = wrap("cor", size = 3, hjust=0.8)))
