This thread is resolved. Here is a description of the problem and solution.
Problem: Avada fonts different on translations Solution: I checked CSS of the translated pages, but somehow font weights were not set, they had empty values so they were basically 400 and not 700 as they are on originals. Since all this CSS comes from Avada theme options, I opened Avada options, switched to English language and set typography there.
If you see any other difference between font styles, I suggest you try the same - checking whether these settings are synchronized between original language setting and translated languages and if yes, set them.
