Row_Number is always 1 when selected after first query

In the below query, when i to a ToList() after first select i am getting correct row index with each record, but when i try to get the result based on where filter i am always getting 1 in return value.

await repository.Query().OrderBy(t => t.DateCreated)
                    .Where(pb => pb.IsActive == true && pb.SiteId == currentBlogPost.SiteId && pb.BlogPostTypeId == currentBlogPost.BlogPostTypeId)  
                    .Select(x => new BlogMinimalInfo { Index = Sql.Ext.RowNumber().Over().OrderBy(x.DateCreated).ToValue(),Id=x.Id })
                    .ToLinqToDB()
                    .Where(pb => pb.Id == currentBlogPost.Id)
                    .Select(pb => pb.Index) ==> this always comes 1 but should be different based on each Id
                    .FirstOrDefaultAsyncLinqToDB();

i need this query to work so i can select prev & next record of current row which is guid Ids. And Enumeration will be bad once database starts growng.

Yes it is a bug. Try to put AsSubQuery() exactly before ToLinqToDB()

@sdanyliv can you look into this?
