'Facebook Pixel and Conversion API events deduplication stopped working

I have manually integrated Facebook pixel and conversion API ecommerce events on my client's website. It was working fine but from 3-4 days, "Test events" tab is not showing deduplication. It does show both server and browser events with same event name and event id but not showing if it's deduplicating it or not. It's happening from 3-4 days. In recent activities, it's showing both browser and server events. Any help will be highly appreciated!
