"home" item is not translated in a bilingual website

I have a big issue with a bilingual website (gantry 5 Rockettheme theme and Grav 1.7.3) All the menus items are correctly assigned to pages and outlines, and the menu is visible in both languages without problem, except for the homepage , which is "Home" in English and "Home" in Irish, while it should be named "Baile" . Also the active link always points to the english version of the page, while it should point to the Irish version.
I've double-checked everything, cleared every possible cache (browser, gantry and GRAV) and built the site 4 times, but I can't solve the problem.
The Rocketheme experts weren't able to help me... what else can I do?

This is the link

@maria,

what else can I do?

You could provide the following info:

• What does the 'languages' section in 'system.yaml' look like?
• What is the frontmatter in '01.home/default.en.md' and '01.home/default.ga.md'?
• Are you using plugin 'LangSwitcher'?

Hi pamtbaau, thanks for your reply. So

1) system.yaml langauages section

      languages:
      supported:
        - en
        - ga
      default_lang: null
      include_default_lang: true
      include_default_lang_file_extension: true
      translations: true
      translations_fallback: true
      session_store_active: false
      http_accept_language: false
      override_locale: false
      content_fallback: {  }
      pages_fallback_only: false

2) default.en.md file:

    title: Home
    cache_enable: false
    process:
        markdown: true
        twig: true

{% include "forms/form.html.twig" with {form: forms( {route: '/form/contact'} )} %}

3) default:ga.md file:

    title: Baile
    cache_enable: false
    process:
        markdown: true
        twig: true

{% include "forms/form.html.twig" with {form: forms( {route: '/form/contact'} )} %}

4) LangSwitcher plugin enabled and working correctly for all the other menu items ("The Hooker", "News", "Resources", "Contacts")

Let me know if there is any other info I can provide

What happens if you set the default language in system.yaml (default_lang: en for eg.)? How does your menu template look like? Seems like Home element is separate from the rest.

@maria, Had a look at your site, pulled the covers... and it appears to be Gantry using a paid theme called Zenith. Which means I cannot download the theme, test it, look at its code, ...

I'm afraid, I can't help you with this one...

@pamtbaau I understand ...thanks anyway!
@Karmalakas I tried to set it to en, but there isn't any diffference
