Remove Unit Price, Total Price and Total from checkout page

-- url of the page with the problem -- : www.aupoop.com/order
-- HikaShop version -- : 3.3.0
-- Joomla version -- : 3.8.5
-- PHP version -- : 7.0.7
-- Browser(s) name and version -- : Chrome 64.0.3282.167
-- Error-message(debug-mod must be tuned on) -- : No Error message

I have tried removing the code suggested in www.hikashop.com/forum/checkout/863859-r...al-price.html#133888 but the Unit Price, Total Price and Total still show on my checkout page as you can see by the circled items on the attached image.

I'm familiar with HTML but struggle with PHP however, I can move my way around it. Thus far, I have had no success and am hoping that someone can tell me why I am not successful at this.

Thank you for any assistance you can provide

Thanks, Nicolas. I will look at the CSS option and eagerly await the next release.

Is there a beta release available? The site I am working on is not a production site and won't be live for a couple of months.
