Please provide any additional information below.

In "Select heal spells" drop-down menu, there are two "Raid Cooldowns" options, create a "status", in "Add heal Spells" drop-down menu, when I choose the first "Raid Cooldowns" option, it's not working, choose the second "Raid Cooldowns" option, just added "Traquility" in the "Spells" textbox.

What is the function of the two "Raid Cooldowns" options?

The first "Raid Cooldowns" are the "Monk" class cooldowns, but this class does not exists in classic, only in retail.

Unfortunatelly i have not a list of valid AOE spells IDs for classic, so the predefined aoe spells are only working well in retail.

I removed Raid Cooldowns option for classic (because the "All Classes" option already include the aoe spells), as far as i know there are only 3 aoe heal spells in classic ( Chain Heal,  Prayer of Healing and  Tranquility).
