Question MudSelect showing Value instead of MudSelect Item - Mudblazor

[Pablo]

Hello again,
So I continued practicing with Mudblazor, and as I learnt EFCore I was able to follow a tutorial about CRUD.
I have in my Index.razor a form to Edit/Add customers, and a table that shows all of them with the options to edit and delete. When clicked the Edit option, that customer's data is shown in the form. The issue is that if in the form there is a country selected that is not the one of the customer selected in the table, I'm able to change it (by code) to the country whose city is the customer's, but in the City MudSelect it appears the Value and not the Item (text of the city) as seen in the image.
I will appreciate any help you can give.
Pablo
