Hi Folks,

I have a property on a page which is an IList of blocks

[Required]
[ListItems(3)]
[Display(Name = "Hero Promo Cards",
    Description = "List of optional Hero Promo Card blocks (min 1 and max 3 can be added)",
    Order = 10)]
public virtual IList<HeroPromoCardBlock>? HeroPromoCards { get; set; }

For some reason this is being read by the CMS as a single block

Have I done something wrong here. I've used the same approach elsewhere in the same project and it works as expected. The only thing I can think of is that this property was originally a content area and changing from that has corrupted the database somehow.  I have reset the content type to code in the settings several times and it is still broken.
