That doesn't make sense since the line of code that is being affected is the following

sub recursion{
        findDir($dir, $min, $max);
}
sub findDir{
    my ($dir, $min_depth, $max_depth) = @_;
}

granted that is a scaled down version, but for brevity's sake you get the idea. No matter what is being passed after $min and $max == 2 is not being updated in the findDir directory. It seems like the array @_ is holding on to old values, but even when I use

$dir = shift;
$max = shift;
$min = shift;
etc ...

I still get the wrong data. This has to be some property of recursion that I am missing...
