Duplicate data with different objectId

I have 56 records in my db. When I import them to algolia it becomes 439 record. Each of them have 8 duplicates (the items I searched).
The object ids are like: "App\Models\Detail::51::7" "App\Models\Detail::51::6" up to `“App\Models\Detail::51::0”.

I am using Laravel 8. And followed the Laravel get started docs.
I don’t know what caused this.

Can you share the related code? The relevant part of the Detail model and possibly other related models.

Are you using Aggregator and the feature to split large records from Laravel Scout Extended?
