Jira Software fields aren't / can't be translated

Greetings,

On Jira Software Cloud, when the user sets his language as Spanish in account preferences, all system fields gets translated but Jira Software specific fields (Epic Name, Epic Link, Sprint, Start date...) remains in English. The field descriptions are partially translated for some of them (it still reads epic instead of epica , for example), and not at all for others (start date).

Also, as these fields are locked, their translation can't be customized per site, so it's nowadays impossible to show these fields in another language, or even change their field description.

These fields should be automatically translated as system fields are, or a way to translate them manually should be provided.

Kind regards,

The issue is with the SLOVAK language as well. Adding a screenshot for reference.
