Facebook catalog sees the event source, but does not see the data source?

Question

Facebook

Hello
Please advise.
A business manager is set up, an ad account is connected to it, and there is a pixel in the ad account. The pixel code is inserted on the site and events are added.
A directory has also been created
. Now the question is.
In the catalog, in the "Event data sources" item, the connected pixel is visible, and in the "product data sources" item, it says that there is no actual pixel.
Micro data is configured according to the Schema.org and OpenGraph schemes
. Please tell me where to dig.
If there is little information, tell me what you need, I just don’t know which screen to attach so as not to clutter up the text of the question.
