Attempts to add a contact creates a blank No Name card
I am currently running macOS Monterey on iMac (Retina 5K, 27-inch, 2017). However, I have had this problem for YEARS and can't figure out what is happening. When I add a Contact, I click on the + and select "New Contact." The blank contact card appears as you would expect. Next, I start filling in the First name, last name, etc. Typically as soon as I enter the "FirstName," the card vanishes. No matter how many times I try. Every time the card vanishes, I can look at the contact list, and there will be a blank card titled "No Name" once every time I attempt to add a contact. I can also click on the +, select New Contact, and then do nothing on the new contact card template. In about 7-8 seconds, the Contact Card will vanish, and there will be a new blank contact card listed as "No Name." It appears the only way I can successfully add further contact is to let the system add the "No Name" card, then right-click the card and select "Edit." Then and only then can I fill in the information and save the card.
I have searched numerous times and have never found a cause or solution for this issue. Although, as I mentioned before, I have had this problem for years on multiple Macintosh computers, desktops, laptops, it doesn't seem to matter.
Any suggestions or possible solutions would be greatly appreciated.
