Bugged Battleground Notifications

[Bluu_Oni]

Hi all,
when i'm in Battleground the pop-up notifications are all messed us.
For example: when i kill someone instead of the correct message, appears written "Block Mitigation", and instead the the name of the teams i have random things like "Physical Critical Damage" or "Block Cost" lol
I attached a couple of screenshots of this.

Can you guys help me figuring out what add-on could be the responsible of that?
Thanks in advance!
