Please choose a purchasable product for the component **product** before adding

Hello,

I still get the error: Please choose a purchasable product for the component **product** before adding this composite to the cart.

In the previous version, I could add a variable product. This does not function any longer in your new version.
I now need to add ALL the variation from that variable product manually into the smart composite product made with your plugin.

Please make this function work again.

I had to downgrade your plugin to version 4.2.0 for it to work again.
So somewhere in your update it stops functioning.

Please fix this.
