I found a bug on Group node permission screen (Edit group type permissions) when I use Japanese language.
Installation scripts as follows:
composer create-project drupal/recommended-project toyota
cd toyota
composer require drupal/admin_toolbar drupal/group drush/drush
cp web/sites/default/default.settings.php web/sites/default/settings.php
chgrp www-data -R web/sites/default
sudo -uwww-data vendor/bin/drush site:install standard --db-url=mysql://DBUSER:DBPASS@localhost:/toyota --account-name=ADMINUSER --account-mail=ADMIN@ulslab.com --site-mail=ADMIN@ulslab.com --account-pass=ADMINPASS --site-name=toyota -y
echo '$settings[''trusted_host_patterns''] = [' >> web/sites/default/settings.php
echo " '^toyota\.ulslab\.net$'," >> web/sites/default/settings.php
echo "];" >> web/sites/default/settings.php
chmod 555 web/sites/default
chmod 444 web/sites/default/settings.php
vendor/bin/drush en admin_toolbar_tools gnode -y
vendor/bin/drush updb -y
vendor/bin/drush core:cron
vendor/bin/drush user:create hagi --mail="SOME@ulslab.com" --password="PASS"
vendor/bin/drush user:role:add "administrator" hagi
sudo -uwww-data vendor/bin/drush en language config_translation content_translation locale -y
sudo -uwww-data vendor/bin/drush config:export -y
After installation (with default English locale), I added Japanese language.
Then I added new group type "meetup"
Then I install 2 (default) content types to Group node and check permission settings with English and Japanese. Both works well.
And then define new content type "temp" using Japanese language
And check "Meetup" group type permission both in Japanese and English. Both not working well.
Both the label of content type was changed to Japanese translation and only one content type was appeared.
If I delete "temp" content type and clear cache then permission screen works well.
If I install drupal with Japanese locale - no multi lingual setting, group type permission screen is not working well. Same to above screen without any content type additon.
WHEN I try same operations with Spanish language instead of Japanese, it seems WORKING WELL.
