Shows incorrect count number by using selectRelationCount previewFeatures

I have a list of posts and each post has multiple comments. I was counting the total comments that each post has. Using selectRelationCount previewFeatures, its count number is correct but it shows different references. like: post id 1 has 2 comments post id 2 has 4 comments post id 3 has 0 comment post id 4 has 0 comment

query result shows: post id 1 has 0 comments post id 2 has 0 comments post id 3 has 4 comment post id 4 has 2 comment

Query:

 ..
 select: {
      ...select.select.posts.select,
      _count: {
        select: { comments: true }
      }
    }
 .
 .
 const posts = await prisma.post.findMany(opArgs);

Have the similar problem here, even without using skip or cursor
