On UI, currently when adding a key-value attribute, eg. 'Edit node labels', it always shows a couple of blank key/value input boxes as default. This gives a hint that the user may need to do something on this, however, they are not the requirement fields. From the user experience and the learning from EKS, as a customer, I'd like it does not show the blank input boxes, but only provide the button to allow the user to customize.
