Been having a similar issue with ‘arenapet’ when it comes to TellMeWhen / WeakAuras, used to be able to track spells from them such as: the cooldown on Intimidation, but it no longer works in this expansion for some reason
Hm weird, I use a macro to target them so I can flameshock or kill them and that works just fine on bm like this:
/target arenapet1
/target arenapet2
/target arenapet3
Hm maybe try this and see if that solves the problem: #Showtooltip
/cast [target=arenapet1, exists, nodead] Paralysis
/cast [target=arenapet2, exists, nodead] Paralysis
/cast [target=arenapet3, exists, nodead] Paralysis
