Ahh ok, so I just tested the macros, and they worked for me. Here's what I did:

/micon "corps-a-corps"
/ac "corps-a-corps"
/chotbar change 2
(Then I mapped it to a slot on hotbar 1)

/micon "displacement"
/ac "displacement"
/chotbar change 1
(Then I mapped it to a slot on hotbar 2)

Try them out. The issue could be that you used "/ability", or maybe the macros somehow weren't mapped to your crossbars and it was still using the normal action buttons.
