With the default UI, when swapping talents the Blizzard Cooldown Manager will remove unknown spells from the Essential Cooldowns list. With this addon installed, the cooldowns will stay "remembered" even though they are not known.

This was an issue I fixed recently. Have you updated the addon lately?

Thank you for the quick fix!

I just started using the addon today. Using version 11.1-060. Downloaded from wowup-cf

Here's how I reproduce it on my evoker:
Spec into a spell, like unravel/firestorm/etc...
Unspec out of that spell.
The spell stays in the Cooldown list even though I do not have access to the spell anymore.

Does it go away if you enter and exit Edit Mode?

Is it still there if you turn this addon off?

The spell is not removed when I enter/exit Edit mode.
The spell is not removed when I log out and log in.
The spell is removed if I remove the spell from the active icons(in edit mode). The spell icon disappears, and does not go to the inactive icons list.
The spell is removed if I click "Reset Cooldown Managers DB" in the options menu

The spell is removed if I turn the addon off.
