Is there a reason you are storing a reference to a reference of an array?

Where you have store( \$baseline, $baseline_records ), maybe instead it should be store( $baseline, $baseline_records )?

This gives me identical output:

use Storable;
use Data::Dumper;

my $baseline_records = 'file.stor';

my $baseline = [
    {   'LICount'      => 0,
        'LICountBase'  => 0,
        'LIFloat'      => 0,
        'LIFloatBase'  => 0,
        'LIICount'     => 0,
        'LIICountBase' => 0,
        'ProjectID'    => 'STO1019001',
    },
    {   'LICount'      => 0,
        'LICountBase'  => 0,
        'LIFloat'      => 0,
        'LIFloatBase'  => 0,
        'LIICount'     => 0,
        'LIICountBase' => 0,
        'ProjectID'    => 'STO1018001',
    },
    {   'LICount'      => 38,
        'LICountBase'  => 38,
        'LIFloat'      => 0,
        'LIFloatBase'  => 0,
        'LIICount'     => 11,
        'LIICountBase' => 11,
        'ProjectID'    => 'STO1005001',
    }
];

store( $baseline, $baseline_records );
my $arrayref = retrieve($baseline_records);

print Dumper $baseline, $arrayref;
