Cannot import lang file 3.0.1.1 => 3.0.1.3, wrong owner /permission on new lang fi

Hello,

i'm not able import exported language file which was exported from 3.0.1.1 to 3.0.1.3. When i click on " Import Selected Language" nothing happens
( i have tried cz.lng also cs.lng as desribed under)

Anyway , when i created new cz (Czech) language file all lang files are created with 644 permission user:group www-data:www-data
compare to 770 on other lang files with user:group ispconfig:ispconfig


Another thing - not important, just weird
i have to input new language as "cz" to create file with correct country flag
but according 2 characters ISO 639-1 language-code http://en.wikipedia.org/wiki/List_of_ISO_639-1_codes code for Czech is cs.
It should be just outdated as Czech/slovak codes had split 15 years ago

 

Should i fix somehow problem 1?

There seems to be a problem with the current release.

Or only way is to copy all files manualy and then merge ?

 

some bigger problem with languages

it seems that there is some genral problem with languages
you can choose any language in TOOLS => Password and Languages
and left main menu stays still in english
