Add to Cart Error

I have created a catalog on the Facebook business manager. It is connected to the Facebook pixel which is integrated on my website. All was working fine till yesterday I got a pixel error stating Redundant purchase events. When I checked the pixel debugger tool i got this error, "The product parameter IDs provided cannot be found in the catalog connected to your AddToCart event. This may cause key features of dynamic ads to not be available" even the product catalog uploaded has the content ID in it.

Anyone can help on this issue will be really appreciated.
