@emmapeel If there is only one bridge with an incorrect format, what value will be placed in %1$d? Since Japanese does not distinguish between singular and plural forms and the translation is unified, if %1$d remains empty in the singular case in English, the translation will not convey the meaning. I think it would be better to use %1$d for both singular and plural forms, like https://hosted.weblate.org/translate/tor/tor-vpn/ja/?checksum=9aa4672a96783048 .
