Hikashop - Switch Buttons on HikaShop Content Module Carousel

-- HikaShop version -- : 6.5.0
-- Joomla version -- : 5.4.3

Hello

I have published some Hikashop content modules in carousel format. I have the "Switch buttons" option enabled, but the buttons are not visible. The link exists, but there's no icon or text to make it visible. Is there a setting to show or hide these buttons? What is the view of this module so I can customize it?

Thanks!
