Theme conflict with Composite Product Plugins

I just buy new theme from, and have problem when i configure a Composite product in Woocommerce with " Composite Product plugins ( license version) : the main menu is disappeared after i add composite product to cart, and it come back if i delete this product.
I try with another theme like frontstore and twenty seventeen, it working fine.
I made a ticket and send to their support, but i haven’t received an answer yet ( for 2 days).
So, i create this topic and hope anyone can help me fix it.
Thank you!
