When you're in an Object with Fields, such as a Contact, and the Field has a value of NULL, HighLevel's UI inserts gray placeholder text that essentially repeats the Field's name. This is fine on online forms (especially when you can define if placeholder text is used and what it says), but this is not really a great standard in database/CRM UI, as you don't want to imply a value is in the field when it is not.
Furthermore, this becomes REALLY confusing in Custom Fields that are one of the "dropdown" field types because (at least in Chrome on a PC), the placeholder text isn't gray... it's BLACK, so it appears like an actual value in the Field. And on top of this, for some reason the placeholder text remains a selection in the dropdown values when you click on it, even though it's not defined as a selectable value in the Custom Field's settings.
