Product Slider shows random products instead of category products

Hello!

I can\'t find the name of my plugin in the list below. It\'s called Product Slider for WooCommerce

I like this plugin, it\'s really functional and customizable. But the only thing makes me upset. I can\'t set a specific category products to be displayed in a slider. Whatever category I set it just displays products from any category. Please, help me to fix this problem.
