Spell Timers not working for some Spell Effects

[Stabaroni]

If I have Thieves Guild cast on me then Organized Crime will show on my Spell Timers window, but if I'm in group with a brig and he has cast it on another group but still proccing it for my group, it won't show up, even though I can see it on the Spell Effects.

The same applies with the SoD celestial familiar 5% Base Damage proc Ethereal Buildup - it will show in Spell Effects but not Spell Timers.

Anyone know why this is and if there is a way to make it work?
