macOS truncated Contacts custom labels

No matter how much screen space is available, using Contacts on my Mini, custom labels (for phone number, email, etc.) are truncated after about 16-17 characters. I have to do a mouseover to read the entire label. It seems that this should be unnecessary when using a 27 inch screen. Does anyone know how to “untruncate” the labels?

Example (not a real phone number): Company Staff Off… (318) 224-3567

Mouseover: Company Staff Office Fax) 224-3567
