Sorry to necropost here, I hope the creator of the NS package can help.
I deployed an instance of NethServer and added NextCloud and Collabora incantations to it. It works pretty well (considering all is deployed on a physical Core 2 Duo E7500-based PC), but the user are complaining about documents not having support for italian formats (dates, decimal numbers, etc.).
As you can see from this screenshot, the UI of the Collabora interface is correctly localized (they are using italian language, check out the menu titles), although for some strange reasons part of the interface uses different language/formats (I shown the “Format cells” dialog in the screenshot).
It may be a slight issue inside NC, but I don’t have any clue on where to check for difference. I tried diffing the /etc/loolwsd/loolwsd.xml file but I didn’t find any meaningful differences.
I also tried to check out if loolwsd has some errors when loading the “Format cells” dialog, but only received a warning:

CODE versions are also slightly different: this is the NS one:
That’s exaclty that! I thought I have checked before the language packages, but evidently used the wrong commands. To fix the issue, I had to manually install the packages collaboraofficebasis6.0-it and collaboraoffice6.0-dict-it (the latter is optional, but it is needed if you want to enable syntax checking) and restart loolwsd service (not sure it was required).
