New fields get created but label is blank

[Tyler Johnson]

Getting a issue where when creating any new fields either on the table itself, Designer, or Form layout after you hit save the field gets created but it reverts to a empty label and does not show on the form. unable to create any new fields now due to this item. 

Received this error
