Woocommerce email templates – Multisite

Hello there. I have a multisite wipeout.cz and wipeout.cz/en (sub-directory) with woocommerce installed (not network activated).

I wanted to customise New account, Processing order and Order completed email templates. But if I make a change on CZ version, it overwrites EN version and vice versa. Woocommerce order fields are ok in correct language, but if I add some text, links etc.(for example in New account template), it always overwrites both language versions because it uses the same template. So I need one template for each lang. version.

I tried to customise core .php templates and hoped that woocommerce’s .pot file will update somehow to be able to translate .po into my language but there are still default template strings.

The only solution seems to be leaving default woo emails completely unchanged :-(, then the localisation works.

This is really the only issue than I can’t figure out by myself from reading support forums, I asked my theme support (flatsome) and they advised me WPML plugin but it’s not a solution for me.

So thank you for any advise.
Best regards Michal
