Issue with discount display on category page

-- HikaShop version -- : 2.6.1
-- Joomla version -- : 3.4.8
-- PHP version -- : 5.5.32
-- Browser(s) name and version -- : all
-- Error-message(debug-mod must be tuned on) -- : none

Several categories have items on sale for 20% off.

We want to show the original price crossed out next to the sale price.
Product pages are correct.

On the category pages, some are correct, but others have the original price displayed as '-20%' instead of being crossed out.

Why would they display differently and how can I make them all the same?

Hi,

You can edit your menu items via the menu manager of Joomla and your modules via the modules manager of Joomla.
In their options, you'll find the "products options" or "HikaShop options" tab.
In there, you'll find the "discount" setting where you can select how the prices with discount should display. Just make sure that they are all like you want and that way is will display the same everywhere.
