Yeah, Ethereal Remedy should be spell type should be 2 for heal, and slot 1.
The others with their max levels:
Pious Remedy 70
Pious Elixir 71
Aura of Devotion 71

UPDATE merc_spell_list_entries 
SET spell_type = 2, slot = 1
WHERE spell_id = (SELECT id FROM spells_new WHERE name = 'Ethereal Remedy' ORDER BY id DESC LIMIT 1);

UPDATE merc_spell_list_entries 
SET maxlevel = 70
WHERE spell_id = (SELECT id FROM spells_new WHERE name = 'Pious Remedy' ORDER BY id DESC LIMIT 1);

UPDATE merc_spell_list_entries 
SET maxlevel = 71
WHERE spell_id = (SELECT id FROM spells_new WHERE name = 'Pious Elixir' ORDER BY id DESC LIMIT 1);

UPDATE merc_spell_list_entries 
SET maxlevel = 71
WHERE spell_id = (SELECT id FROM spells_new WHERE name = 'Aura of Devotion' ORDER BY id DESC LIMIT 1);

This is untested, but should work.

Good catch.
