How to reproduce (e.g Puppet code you use)

  class { '::hiera':
    create_keys        => false,
    master_service     => 'puppetserver',
    manage_package     => true,
    provider           => 'puppet_gem',
    eyaml              => true,
    eyaml_version      => 'latest',
    eyaml_datadir      => '/etc/puppetlabs/code/environments/%{::environment}/hieradata',
    eyaml_extension    => 'yaml',
    eyaml_gpg          => true,
    ruby_gpg_version   => 'latest',
    merge_behavior     => 'deeper',
    deep_merge_version => 'latest',
    backends           => [
      'eyaml',
    ],
    backend_options    => {
      'eyaml'      => {
        'gpg_gnupghome'    => '/etc/puppetlabs/puppet/keys/gpg',
      },
    },
    hierarchy          => [
      'nodes/%{::trusted.certname}',
      'common',
    ],
    deep_merge_options => {
      'knockout_prefix' => '--',
    },
  }

What are you seeing

hiera.yaml does not contain

:deep_merge_options:
  :knockout_prefix: --

What behaviour did you expect instead

hiera.yaml should contain

:deep_merge_options:
  :knockout_prefix: --

Any additional information you'd like to impart

I have submitted PR #172 to fix this.
