What steps will reproduce the problem?
1. Dual spec a Death Knight, preferably a Blood Elf
2. Spec exactly one of the specs Unholy with Improved Unholy Presence and the other spec either deep blood or deep frost
3. Check buttons after re-talenting.

What is the expected output? What do you see instead?
Expected: Addon remember button saves.

Unholy Presence: button constantly changes to Improved Unholy Presence (passive talent) and is unclickable
Anti-Magic Shell: button constantly changes to Magic Resistance (passive racial) and is unclickable

This happens with other abilities, but those two are continual culprits. Some abilities are somtimes just forgotten, this in particular for talented abilities.

What version of the product are you using?
v.1.04

Do you have an error log of what happened?
No error logs are generated.

Please provide any additional information below.
A work-around is to keep EVERYTHING as a macro. Linking buttons to macros instead of actual spell abilities.
