Thank you for contacting WPML Support. In this case, I would recommend a custom code to display the language switcher in your single product template file. Something like:
1 - Look for the single product template file of your theme and copy it to your child theme in case you are using a child theme (Note: it is always recommended to make any theme code customization using a child theme, doing it this way you avoid loosing your changes in case of theme updates).
