Hi @Bluenotes

Thanks again for the bug report.
I have tracked down the issue and have a solution for you.

The issue stems from the get_field function. This function is a theme friendly helper function which also formats the returned value. Because the text area has an option to convert any line breaks to the ‘br’ tag.

So your $choices value actually contains br tags! You can check this with some simple debugging.

This explains why values won’t save (because the MARKUP is invalid – br tag within select option’s value attribute), and why the field’s choices setting looks odd.

All you need to do is improve your function like so:

function bne_team_schedule_team_names_load_field( $field ) {
	$field['choices'] = array();
 
	$choices = get_field('bne_team_schedule_team_names_options', 'option', false);
 
	$choices = explode("\n", $choices);
	$choices = array_map('trim', $choices);
	
	if( is_array($choices) ) {
		foreach( $choices as $choice ) {
			$field['choices'][$choice] = $choice;
		}
	}
 
    // Important: return the field
    return $field;
}

Please note the 2 changes:
1. get_field function is using the 3rd param to prevent formating
2. arrray_map function will trim any white spaces from the value!

Hope that helps.
Thanks
