ggplot2 axis

Dear users,
Does anyone had a problem with ggplot concerning the axis not being 
shown? (see attachment)

ggplot(db, aes (x = lenght, y = width, color = support)) +
 ? geom_point(size=2) +
 ? stat_ellipse() +
 ? labs(x="Lenght (mm)", y="width (mm)", title="Boxplot", color = "Support")

I'm using the following version: ggplot2 3.3.0.

Thank you for your help.

Joao M.
