Defining the commitPartial voids other wirter and presetConfig options

I have the .releaserc as

- - "@semantic-release/release-notes-generator"
  - presetConfig:
      issuePrefixes: ["xyz-", "abc-"]
      issueUrlFormat: "https://my.atlassian.net/browse/{{id}}"
    preset: conventionalcommits
    writerOpts:
      commitsSort: ["subject", "scope"]   
      commitPartial: |-
        * {{header}}
        {{~!-- commit link --}} {{#if @root.linkReferences~}}
          ([{{hash}}](
          {{~#if @root.repository}}
            {{~#if @root.host}}
              {{~@root.host}}/
            {{~/if}}
            {{~#if @root.owner}}
              {{~@root.owner}}/
            {{~/if}}
            {{~@root.repository}}
          {{~else}}
            {{~@root.repoUrl}}
          {{~/if}}/
          {{~@root.commit}}/{{hash}}))
        {{~else}}
          {{~hash}}
        {{~/if}}
        {{~!-- commit references --}}
        {{~#if references~}}
          , closes
          {{~#each references}} {{#if @root.linkReferences~}}
            [
            {{~#if this.owner}}
              {{~this.owner}}/
            {{~/if}}
            {{~this.repository}}#{{this.issue}}](
            {{~#if @root.repository}}
              {{~#if @root.host}}
                {{~@root.host}}/
              {{~/if}}
              {{~#if this.repository}}
                {{~#if this.owner}}
                  {{~this.owner}}/
                {{~/if}}
                {{~this.repository}}
              {{~else}}
                {{~#if @root.owner}}
                  {{~@root.owner}}/
                {{~/if}}
                  {{~@root.repository}}
                {{~/if}}
            {{~else}}
              {{~@root.repoUrl}}
            {{~/if}}/
            {{~@root.issue}}/{{this.issue}})
          {{~else}}
            {{~#if this.owner}}
              {{~this.owner}}/
            {{~/if}}
            {{~this.repository}}#{{this.issue}}
          {{~/if}}{{/each}}
        {{~/if}} - {{author.name}}

As soon as I define the commitPartial in the config the other default and defined options are not respected; when it is present the issues are not linked, the commit sha is not transformed to 7 chars.
Removing it make the other things work. Am I missing something here?
The template is the default one picked from the repo... we just added the - {{author.name}} at the end

Start with the .releaserc configuration and the default commitPartial template from the repository, comparing output with and without commitPartial. Verify whether issue links and seven-character commit SHAs remain enabled while the custom author suffix is preserved; done means all configured options work together.
