If the site is a multisite or has language version-specific domains, you most likely have a distribution for each of them. To define multiple distros, use the format DISTRIBUTION_ID_[blog id]_[language slug]

DISTRIBUTION_ID_EN = no multisite, english language
DISTRIBUTION_ID_1 = multisite, main blog selected, no language-specific domain
