Unit price error when multiple items in pack.

The app shows the item price, and below it the unit price, ie. per 100g; 100ml; etc Some packs also show how many items per pack. The app appears to be correctly dividing the price by the unit, but the error is that it is also dividing that result by number of items contained in a pack. Example: https://www.trolley.co.uk/?p=CNX864 This shows Sainsbury's pork loin steaks at 800g for £6.25. The packet price is £6.25 divided by 8, which is £0.78125 per 100g. However the app incorrectly shows the unit price as £0.10, this is because it is also dividing the unit price (£0.78125) by the number of items shown to be in the packet. This error appears to apply to many or possibly all packages that are shown to contain multiple items.
