Help on Abilities editing???

I was making a new abilities that hav 10 levels in it and my abilities is about evasion so i make it and when i scroll down in the world editor for editing the-
-- Level 1 - Text - Tooltip - Normal - Extended: --

For example
-- Level 1 - Text - Tooltip - Normal - Extended: Gives a <A003:AEev,DataA1,%>% chance to avoid an attack.
What does

<A003:AEev,DataA1,%>%

mean, and i do i make it work, im really lost now i hope some professional in this could help me...

lets make this more simpler i copy a abilities from a map of my friends that is call Evasion Skill it got 10 levels for it, but when i change the abilities name for the Evasion Skill to Evasion Mastery...Then it start to not work ...

You know when you learn a level and you choose the abilities you want it say for example "This abilities give you 8% that enemy will miss you..."
When i change my Abilities name it doesn't show the 8 percent it say "This abilities give you 0% that enemy will miss you..."

Any way to help me plz

2 options:

1) Scream at blizzard and hope they fix it in the next patch.
2) Replace the <A003:AEev,DataA1,%>% with 8%, and then use auto filler I think. It might now work, then it takes a while.
