Got stuck in Expanding the domain model - Rapid Certification

Hi all! I got stuck into Chap. 5 (Expanding the Domain model) specifically when I have to generate a NewEdit page using the Reference Selector widget. The training requires me to do a series of steps (which I have done):   Expand the domain model by associating the new entity "TrainingEvent" to the other 3 existing entities: Course, Location, and Teacher (as in the picture)     To create a new page "Training Event" and to connect it to the TrainingEvent entity, without automatically filling the contents of the list view To configure the list view to the different parameters: Course, Location, and Teacher To create a button and connect it to the TrainingEvent entity The challenge arise when I am tasked with creating a NewEdit page because in the training it shows that I should have a page like this.     While I am currently having this:     In addition, I am also getting this error     Your insights would be really helpful at this stage! Thank you in advance!
