Too exhausted to scold, move hooks outside of hooked events/frames/functions.

Like so, and problem solved(maybe? not tested).

--removed stuff with no purpose
 
hooksecurefunc("CompactUnitFrame_UpdateName", function (frame)
   --Set the tag based on UnitClassification, can return "worldboss", "rare", "rareelite", "elite", "normal", "minus"
   local tag 
   local level = UnitLevel(frame.unit)
   if UnitClassification(frame.unit) == "worldboss" or UnitLevel(frame.unit) == -1 then
      tag = BossTag
      level = "??"
   elseif UnitClassification(frame.unit) == "rare" or UnitClassification(frame.unit) =="rareelite" then
      tag = RareTag
   elseif UnitClassification(frame.unit) == "elite" then
      tag = EliteTag
   else 
      tag = ""
   end
   --Set the nameplate name to include tag(if any), name and level
   frame.name:SetText(UnitName(frame.unit).." ("..level..")"..tag)
end)
 
-- deleted whatever was here
