teamPlayerID bug

Hello. I found that the property teamPlayerID in GKLocalPlayer.local does not match with property of instance
match(GKMatch).players[0] on other device
example:
1st device
me: T:e96ffe8e2c2113a1081345d8175dd34a,
enemy: 159791492614296288

2nd device
me: T:5445ac43188d54e227751262416576f2
enemy: 159791492784529792

---

While if I use the deprecated property playerID, it works perfect
1st device
me: G:1459229978
enemy: U:b128518d718a7a11e43d83f33a7e43cb

2nd device:
me: U:b128518d718a7a11e43d83f33a7e43cb
enemy: G:1459229978
