customer receipt: phone/email shows up greyed out and refuses to autopopulate

[FollowingCairns]

After swiping customer card, on the receipt option page, customer's number and/or email is greyed out. I can see that the phone number is registered or used with square before, but is greyed out and cannot click to autopopulate. Why?
