Thank you for contacting WPML Support and sorry for the bit of waiting here. This button is being added by a third party plugin not default to WooCommerce, in this case I recommend you to try the following:
1 - In your WordPress Dashboard > WPML > Theme and plugins localization > String in the plugins settings click to check and scan the strings of the plugin that adds the 'Select Service Point' button.
