Wrong LV2 translations loaded

[lucianodato]

Hi I'm the developer for noise-repellent plugin (https://github.com/lucianodato/noise-repellent). The plugin has translations for 3 languages (English, French and Spanish) which are working well in for example Ardour.

I've read about locale issues as indicated here https://forum.cockos.com/showthread.php?t=210390 but couldn't make it work in Ubuntu 20.04 with version 6.36

These are my current locale

LANG=en_US.UTF-8
LANGUAGE=en
LC_CTYPE="en_US.UTF-8"
LC_NUMERIC="en_US.UTF-8"
LC_TIME="en_US.UTF-8"
LC_COLLATE="en_US.UTF-8"
LC_MONETARY="en_US.UTF-8"
LC_MESSAGES="en_US.UTF-8"
LC_PAPER="en_US.UTF-8"
LC_NAME="en_US.UTF-8"
LC_ADDRESS="en_US.UTF-8"
LC_TELEPHONE="en_US.UTF-8"
LC_MEASUREMENT="en_US.UTF-8"
LC_IDENTIFICATION="en_US.UTF-8"
LC_ALL=en_US.UTF-8

and reaper is configured to use English as the language.

Here is a sample session with a loaded plugin. https://drive.google.com/file/d/1Yh8...ew?usp=sharing
The plugin can be downloaded from github releases and installed like any lv2

Is this a known issue? Am I doing something wrong?
