Hi Slastik,

Thanks for contacting us here.

I've read your description of issue, however, I still don't get it right. You're mentioning the Composite Products but your product link is a normal simple product with Bought Together products, not a Composite Product. 

First of all, please make sure you have created the right deal you want. Kindly refer to the online documentation of our plugins here:

WPC Composite Products: https://doc.wpclever.net/wooco/

WPC Frequently Bought Together: https://doc.wpclever.net/woobt/

After checking these out, if you still have any questions, kindly ask then I will try to explain it to you.

Best regards.
