Products category displayed column instead below

-- HikaShop version -- : business
-- Joomla version -- : 3

When displaying the products from a category (with title, image and description) I have a problem with the layout. The products are displayed near each other instead of below each other and also overlay each other. When I select bootsrap on the product are displayed in right way but then the view of the categories is not the way as I need (see attachement).

Any ideas what I did wrong?

Hi,
1. Can you show me how did you configured your category listing content menu ("Hikashop->Display->Content menus->'Your cateogry listing content menu'") and the associated product listing module of your category listing content menu through some screenshots ?
2. Can you tell me what do you exactly want to do with your product listing ?

Hi, thanks for your help.
About your questions I added 2 screenshots

Hi,

With your screenshots we don't see how you have configured the products display.
Thanks to check the configuration of the associated module of the menu "webshop", and see if the display is in one column.

You can too have a problem with your template, it's maybe overriding our css properties and broke the display.
Thanks to check that with your browser console, here is some documentation:
