“Minutes” strings translation issues

Hi,
I’m having a very stressful issue translating the ” %s minutes ago” string in Italian language.
I translated all the necessary missing strings of this plugin in Italian using Loco plugin, and in particular this is the MINUTE translation:

Unfortunately, the front end of a question keeps showing a strange “mistranslated” word as follows:

The word seems to be broken with this layer: MINU[tou]TI (also with other languages like french).
I found out a similar issue with french translation, and here the word is broken in the same way:

I also searched into some PHP files and JS scripts without success. Do you have any information about this problem?

Thanks in advance!
