Probleme with price, variant and add to cart

Hello, I try to configure a “bopo bundle” product with a list of product choices.

I see several issues:
– the price is displayed at 0€ at the level of the summary sheet of the product as well as an option of the woodmart theme “sticky price footer” (see screenshots 1 and 2). The price is displayed correctly in the standard price tag at the detail level
– the add to cart does not work correctly. I am using the wpc fly cart plugin (see screenshot 3). Add to cart works correctly with frequently purchased together product options
– when I select a default product in the back office, the price displayed in the front office does not match (see screenshots 4 and 5)
– finally with your plugin frequently purchased together, impossible to select product variants (screenshot 6)

Therefore I can’t use your plugin correctly. Can you help me ?

Regards,
Manuel
