i18n does not work in the Tiles of my Fiori Launchpad service

Greetings.

The title of my post pretty much describes the problem.

I am working on a project based on SAP CAP, SAP HANA DB, and SAP Fiori Element in the SAP BTP environment (Trial account). I have also configured the Launchpad service to display my apps.

As it is a test solution, it should preliminarily support only two languages: English and Spanish. According to this, I have two resource bundle files: i18n.properties and i18n_es.properties. For each app, the texts for the title and the subtitle of the tiles (flpTitle and flpSubtitle) in the Launchpad are defined in both languages.

However, when the language of my computer is set to Spanish, the Launchpad tiles continue to show the texts (title and subtitle) in English. Internally, each app does show its texts in Spanish when appropriate. The problem is only with the Launchpad tiles.

Any idea of the cause of this problem?

What can I do to fix it?

Thanks in advance for any help and/or suggestion.
