Need Help with some language strings

My Installation:
Joomla:3.10.12
CB: 2.9.3+build.2024.09.10.14.21.57.794f9ce0d

Problem:
I have some difficulties with the following language string:
 

according to my analysis there is the following language string 'behind' this string

'YOUR_INVOICES_OF_LAST_S_b465cf'    =>    'Your invoices of last %s',

So I added (via override) the corresponding strings for the languages DE / IT / SP ..... the result is as follows:

DE:        "persönliche Rechnungen der letzten 5 Jahre"     ....... correct
EN:        "Your invoices of last 5 years"                           ........ correct
SP:        "Sus recibos de los ultimos 5 years"                 ........ not correct
IT:          "Le ultime fatture 5 years"                                ........ not correct         

As you can see the %s part of the language string will not be correctly translated in SP od IT ..... 

Where do I have to adapt and what has to be adapted in order that this translation works?

For time period texts you'll need to translate their respective keys as well. The below are a few for example.

Key: X_YEARS
String: one year|[X] years

Key: X_MONTHS
String: one month|[X] months

Key: X_DAYS
String: one day|[X] days

These strings use counting API. So if the number of years/months/days is 1 then the text before | is used. If it's greater than 1 or 0 then the text after the | is used and [X] is replaced with the number.
