All of the sudden metada from one model is not being generated, here is the class declaration:

class ConsignmentProcessEpt(models.Model):
    _name = 'consignment.process.ept'
    _inherit = ['portal.mixin', 'mail.thread', 'mail.activity.mixin']
    _description = 'Procesos de Consignación'
    _order = "date desc, name desc, id desc"

Here is a screenshot of the metadata: https://pasteboard.co/AaHjoDaFQvjI.png
