I use the fviz_pca_ind() to draw a PCA plot, but the pointsize is deifferent.
this is my code:

library(FactoMineR)
library(factoextra)
pca.res <- PCA(iris[, 1:3])
fviz_pca_ind(pca.res, 
               geom.ind = 'point', 
               col.ind = iris$Species, 
               addEllipses = T, 
               palette = 'lancet')

and this is the results, as circled in the red box, the point is bigger than other.

So, why did it happened?

And, i saw the fviz_pca_ind‘s code, i found the pointsize control by the code

    if (nrow(df) != length(pointsize)) 
      pointsize <- 1.5
    df[["pointsize"]] <- pointsize
    pointsize <- "pointsize"
  }

but it doesn’t seems to be the reason for the different in pointsize.
