Why does my Json Deserializer return 0 for all numeric values, but Swagger returns the correct values?

Description

I'm working on writing a Blazor app using .NET 8. I've got a database with column names that have embedded whitespace. When I deserialize it all the numeric values (SMALLINT in a SQL Server database) are 0 (for example the column "Video Number"), which is wrong and doesn't correctly show what's in the table. However, when I check the values using Swagger, it is perfectly correct. I had thought that the attribute JsonPropertyName would resolve my issue, but it doesn't. Here's my class

public partial class Entry
{
    [Key, Column("Video Number", Order = 0)]
    [JsonPropertyName("Video Number")]
    public short VideoNumber { get; set; }  

    [Key, Column("Entry", Order = 1)]
    public byte Entry1 { get; set; }

    [Required]
    public short ShowCode { get; set; }

    [Required]
    public string EpisodeName { get; set; } = null!;

    public DateTime? ActualPlayTime { get; set; }

    public bool Completed { get; set; }

    public string? Comment { get; set; }

    public TimeOnly? ActualPlayTime1 { get; set; }

    public virtual Show Show { get; set; } = null!;

    public virtual Video VideoNumberNavigation { get; set; } = null!;
}

And here's the code snippet where I'm trying to read the data out of the table:

var contentStream = await httpResponse.Content.ReadAsStreamAsync();
var bozo = await System.Text.Json.JsonSerializer.DeserializeAsync<Entry[]>(contentStream, new System.Text.Json.JsonSerializerOptions { DefaultIgnoreCondition = System.Text.Json.Serialization.JsonIgnoreCondition.WhenWritingNull, PropertyNameCaseInsensitive = true });
return bozo;
