This thread is resolved. Here is a description of the problem and solution.
Problem: I am trying to translate menu items in the food and drink menu pro plugin. The author says that this plugin is compatible with WPML but the price value is not copied to the translated menu item. Solution: Edit the English version of the products missing the price, scroll down to the bottom of the page, press the Apply button in the Custom fields section (to copy the price value), and update the product. Another method that you can try is to set Use WPML's Translation Editor to off and create the translation of the menu items using the default WordPress editor. This way you'll be able to add all the properties to the translated product without being worries that something might be missing or not copied from the original product.
