I have this code which reads words from input file, then it should remove all stop words and count words which aren't stop ones. When I have output, it shows me strange result like this:

hello        1
welcome        1
world        1
hello        1
our        1
page        1
to        1
welcome        2
world        1

What am I doing wrong here and how I am suppose to change this code to work properly? There is my code down below.

#!/usr/bin/perl

use strict;
use warnings;

use Lingua::StopWords qw(getStopWords);

print "Enter the name of your input file: ";
chomp( my $file = <STDIN> );
my %found;

open my $fh,  '>', 'output2.csv' or die "Can't open this file: $!";
open my $fh2, '<', $file           or die "Can't open this file: $!";

my $stopwords = getStopWords('en');
while (my $line = <$fh2>) {
    my @words_all = split /\s+/, $line;

    $found{$_}++ foreach split /\s+?/, $line;

    my @words_nostop = grep { !$stopwords->{$_} } @words_all;
    #print {$fh} join( ' ', @words_nostop ), "\n";
    print $fh $_, "\t\t", $found{$_}, $/ foreach sort keys %found;
}

close $fh2 or die "Can't close file: $!";
close $fh  or die "Can't close file: $!";
