Missing user points and discount from order administrator notification mail

-- url of the page with the problem -- : www.vitaking.ro
-- HikaShop version -- : 3.4.0
-- Joomla version -- : 3.8.8
-- PHP version -- : 7.1
-- Browser(s) name and version -- : Firefox (doesn't matter)
-- Error-message(debug-mod must be tuned on) -- : No error message

After upgrade from 3.3 to 3.4 there are no information displayed in the order administrator notification mail regarding the used points and the obtained discount. I couldn't find any option for this in the settings of the plugin. Also, I have deleted the customization of the email, so right now we are using the default from 3.4. , still no information about wether the customer used some points and obtained a discount or not. We need to check the admin page to have this information, but this could lead to errors, so we need this as before the upgrade. Please help.
