How To Edit extensions.js file in Custom Interface ?

[bogdan]

I'm trying to edit the translations from the javascript section in custom interface to another language than english/russian, more specifically the extensions.js file because there are lines that are not present in the custom interface by default to edit
The lines i'm trying to translate are in the capture below

What i did is i've downloaded the file from BAS servers ==> translated the content ==> uploaded the edited file to my server ==> updated the file path into the BAS "Links to js files." ==> saved changes on BAS custom interface.
Nothing changes when i open the software interface, its the same old translation

It is very sad that such questions remain unanswered. I'm having the same problems but I can't find a solution.
