Describe the bug

Wrong time for druid Rake ability DoT effect (12 sec instead 9 sec).
WoW Classic version.

Aura duration in classic are handled by LibClassicDurations, please open a ticket at https://github.com/rgd87/LibClassicDurations/issues

Hi, I'm posted ticket at https://github.com/rgd87/LibClassicDurations/issues & they ansewered, that in lib is all OK. Then i checked string in my ...\World of Warcraft_classic_\Interface\AddOns\WeakAuras\Libs\LibClassicDurations\classAbilities.lua
Spell({ 1822, 1823, 1824, 9904 }, { duration = 9, stacking = true }) -- Rake
It's looks like right, but problem still ingame. Please, look at this:

WeakAuras does absolutely no duration calculation. We simply use the value that the lib gives us. So I doubt that the bug is in WeakAuras.
