That is true. One famous example where perhaps this went wrong are the jam doughnuts in pokemon. The heroes are eating some rice balls (onigiris) on the screen and perhaps to make the snack more relatable the US dub translates it as jam doughnuts. Which was probably a good choice when one can only see the script, but when on one can see something which is clearly not a jam doughnut it causes some confusion. :)

Similarly somehow in the Hungarian translation of the Harry Potter books they translated Slytherin's Locket as Slytherin's padlock. (which was probably just a mistake) And when in later books it become clear by the character's interactions that it is very much not a padlock they just changed the translated name like it never happened. :D

I don't envy translators. It is a really hard business. Especially for dubs, they don't just have to match the meaning and the emotion, but also have to match the lip flaps too. Not easy at all.
