Team technical ID is not unique (Leaderboard TBCC)

Hello,

While testing my application, I noticed an error in the team IDs. IDs should normally be unique and several teams have the same ID. For example for the 2v2 teams : CNINE DOGS (realm: faerlina), peepoSus (realm: grobbulus), oWN (realm: arugal) are ID = 1.

Endpoint :

/data/wow/pvp-season/1/pvp-leaderboard/2v2?namespace=dynamic-classic-us

Are the team IDs unique for each realm?

Thank you !
