Describe the bug

If you use %1.n, %2.n, etc. with a Spell Known trigger, you just get back the name of the aura, not the name of the spell

To Reproduce

1. Create a Spell Known trigger with a spell
2. Use %1.n in the text to display

Which version of WeakAuras are you using?
2.15.5

Are you on World of Warcraft Classic or Retail?

• Classic
• Retail

I fixed this locally by adding:

    nameFunc = function(trigger)
      return GetSpellInfo(trigger.spellName or 0);
    end,

to the Spell Known entry in the WeakAuras.event_prototype array (Prototypes.lua). This fixes the problem.

Create a Spell Known trigger with a spell

Which one ?

There is only one "Spell Known" entry in the event prototype array. It's under 'Status' (as the type) in the menus. It doesn't matter which spell you choose.
