Yup, that did the trick! Thanks, Nikola.

I guess i won’t be able to update the plugin, though?

The filter that worked for me was ‘bogo_available_languages’.
The ‘bogo_languages’ changed the display language only in the Admin area.

The first changes the links $name, just what i needed. The display languages in the Admin area stays the same.

Cheers!

My code:

function adapt_bogo($lang) {
	$long = array("English", "Russian");
	$short = array("EN", "RU");
	$lang = str_replace($long, $short, $lang);
	return $lang;
}
add_filter ('bogo_available_languages', 'adapt_bogo');
