Ver 6.10 Italian Localization missing table.rowsCount.msg2Singular1

I tried installing the it-localization addon, but this entry is missing anyway.
What is worse, while locally the text falls back to “1 row”, in production tables with 1 row only show the message name: “table.rowsCount.msg2Singular1”

You can fix the translation in your own project. Add to the main message pack of the main module:

table.rowsCount.msg2Singular1 = %s row

Hello!
This is exactly what I did to solve my problem, but, it showed up after switching to the latest Cuba 6.10 so maybe translation addons need an update. Just saying
Thanks
