Search in home page leads to default language

Hi,

I am configuring WPML for my GD WP-MultiSite main site https://inforoses.com using GD Supreme Directory theme and Beaver Builder.

I set a WP page as home page in which the GD Search form appears. This page has been duplicated using WPML because its contents are the same for all languages. Only the strings within the GD Search form have been translated using WPML String Translation.

I am trying multilanguage only with a CPT with two categories and three posts duplicated with WPML. There are other 68 posts not translated neither duplicated.

When using the GD Search form from any language, the GD Search page is always shown in the main language (catalan) with all the 71 posts.

Then I switch language from there and the GD Search page appears as it should in the correct language with only three results for all languages except for the main one.

So I conclude that I did something wrong or I am missing something to do with the home page translation, since its GD Search form does not work as it should, but I can not guess what.

Your help will be greatly appreciated.

I look forward to your reply.

Thank you very much once again for your attention.

Best regards.
