Yes I am using factoextra.

Then, the question is why the legend is not in 0 to 1 scale?

When you choose the argument "contrib" the colors are based on the strength of the relationship overall (the length of the arrow), not the contribution of any individual direction. See here http://www.sthda.com/english/wiki/factoextra-r-package-easy-multivariate-data-analyses-and-elegant-visualization and the various other sources of documentation for the packages.
