[Fechado] Some translations keep getting overriden with original language

WooCommerce store with Bricks builder and Advanced custom fields. Original language is slovenian, then we have translations german, english, dutch. At first we let all the content be translated automatically, but now we want everything to handle by ourselves, so we changed from WPML translator to WordPress translator.
Now when I change text on german version of product and save it, sometimes the content on german product is changed to slovenian language. Sometimes it changes all (description, custom fields...), sometimes it changes just parts of text. And in some cases, when I edit german product and after saving changes to slovenian, also on the english translation of that product the content is changed to slovenian.
