Need help with "channel"

I read that a hero cannot have multiple abilities from the same origin (and that I wasted an hour at it before I read the post), but except channel.

So I created 3 new abilities using channel and given each of them a unique base ID. However, it still confused and no matter which ability i used, the trigger only recognize it as the first ability........

How can i solve this?

You need to change one/both of the folllowing (not sure which) in the abilities:

Data - Base Order ID
Text - Order String - Use/Turn On

Just pick a new order string, one that any unit(s) with the ability won't have a conflict with. Like don't give them the 'blink' order string if they have an ability based on Blink.
