I solved it. I went back and deleted the “brand” field, and recreated a “manufacture” field. then just copy&paste everything in there. then it works! really wield.

I var_dump the object:
$field = get_field_object('brand');
var_dump($field);
And below is what I have got, the value is herman jansen: HERMAN JANSEN, that’s what showed up on my front end every time, what code should I use to only show “HERMAN JANSEN”?
