i've many product , most of them are composite products , and each product is somehow the composite of an other , i dont know why some product are not displayed as composite even though everythings is set up correctly like in the screenshot below , as you see in the product setting there are two product , but in the website live only one is displayed , for some products it working and for other no , i can't figure out why ?

i have made several testes , are the composite working only for simple products ?
