Problem: I have a site in NL and FR. On this site I'm using Woocommerce to show different listings. These listings have an ACF field group linked to it to offer more information. One of these fields is a checkbox field. I want the user to be able to create the product for one language and that it copies his selections over to the other language.
Solution: I have consulted our specialists about ACF and they recommended to not use labels coming from get_option in the front end but simply put _e( 'my label', 'mytheme' ) and translate them with string translation.
In the next version of ACF Multilingual plugin this issue should be solved, but in the meantime, the best solution is to print the labels of the ACF as normal strings and then translate those strings using String Translation.
