Did you take the email action out of the Apply to each loop?
And as for formatting that array, you should be able to put that dynamic content for Country in the From field of a Select action, select the button on the top/mid right side of the action to switch out of the table view, then in the now unformatted box, you can put the expression
item()?[‘Value’]
to get an array of just the Value piece with the country & country code.
Then you can use the
String(body('Select'))
expression to get just the array of Values from the Select action into the email. If you want to format it further, you can add replace expressions around that string expression.
