[Koha-translate] Can't suggest a translation

[Victor Grousset/tuxayo]

Hi :)

On this string
https://translate.koha-community.org/it/20.05/translate/it-IT-messages.po#unit=13403579
I'm trying to suggest:
Vi sono {count} suggerimenti archiviati.

But nothing happens when submitting.
Today I was able to do some suggestions so I don't know why it is 
failing (silently...) here.
Any hints? Or an Italian reviewer or admin who could directly fix the 
translation.

I'm trying to fix this because it raises an error that must be 
circumvented each month when doing the 4 minor releases of Koha.

Cheers,
