Welcome to the Q&A Forum

Hi Greg, As Moz's Open Site Explorer (like most other link indexing tools) crawls sites independently to discover links pointing back to your site, there is often disparity between the numbers reported between of them and with what Google reports in Search Console. That being said, Moz will likely find these links eventually, they just may be in the queue for indexing, or were not present the last time Moz visited those site's pages. Thanks, Jake

if English is your default language, keep that at the root (which I already see you guys implemented- nice!) and use subfolders for the remaining languages. be sure to use hreflang markup to let crawlers know which pages are translated versions of which pages.
