Events missing some deduplication

Hey there (again), maybe in some time with your community I’ll be a really experienced user in Server Side, but right now I’m not…, but your community really helps increase understanding the logic of all that process
After installing all the deduplication processes and seeing that deduplication is coming on the server, I received the error from Facebook that tells me that some of my events are not deduplicating, but the test events section is showing that they deduplicate. What can be the problem?

Thank you in advance for your answer!

How I understand from this topic Facebook Conversion API user_data you already find and fix the issue. That’s right? Or do you still have duplicates?
