Supercharger Cable Pins Loose or Missing

I had an interesting experience at a supercharger yesterday in Augusta Georgia. I attempted to plug in my Model 3 but the cable would not insert. Looking into the supercharger cable I could see the two large current sockets and on the inside of each socket a pin. One of the pins was loose in the socket and off center which must have been stubbing against the interfacing surface of its mate in my M3. I could giggle the cable and see the pin moving in the socket. So I moved to another stall and inspected the cable. To my surprise this cable was missing both pins in its sockets. The other 4 cables I checked were also missing their pins in their sockets. Fearing the worst I drove to another close by supercharger and the stall I chose had a cable missing its center pins also. I plugged in and charged without an issue. The pins appear to be electrically connected to the socket in the cable but insulated in the car. If the pin were to break off while plugged into the car future charging attempts at a different location would not be possible if the charge cable still had its pins. I was surprised to find 6 of the 7 cables I checked were missing these pins. I thought I might be going a little nuts and checked my Tesla mobile charge cable at home. It does still have its pins. Do these pins serve any purpose possible related to temperature sensing of the contacts or are they intended to just help guide the contacts during mating?
