Facebook Dynamic Retargeting Doesn't Work

hello community, I connected my store and Facebook pixel from the official Facebook channel, I also created a catalog with it. The pixel works and records all events, but for dynamic retargeting, events are not tracked. I sell iPhone cases and each case has a color variant and these products are transferred to the catalog as a group of goods. But although the pixel helper shows that the pixel is working correctly, there is still no id match for dynamic ads, I suspect that this is due to the fact that the pixel tracks, not the product id but the product group id (this is indicated by the pixel helper content_type: product_group), therefore it cannot compare data for each individual product. What to do so that the product ID was tracked, and not the group, and the dynamic retarget worked?
