Only use FPD on certain pages causes problems

Hellow,

I ran into a problem.

I am using FPD on one page and disabled it on all other pages.

On the non-FPD pages I am selling regular Woo Commerce products.

The add to card function is not working correctly.

FPD seems to "take over" the "add to cart" function, also for the regular pages.

The regular non-FPD products are NOT bein added to cart when I use FPD.

Any idea?

Regards,

Brenda
