Why ?

Why the Set IA function on the first button left bottom row page 8 brings me back to page 7 when I switch it ON whereas the other buttons (that don't have the Set IA command) work fine ?
(I use CC# 15 to bypass the H9)

The Delays button (page 1, button 4) has IA ID 15, and has a System / Page:7 action on it. When you press the Wah button on page 8, its Set IA action turns on the Delays button on page 1, causing a change to page 7.

Thank you so much Ron.
I hadn't realised that a SetIA function also execute the IA actions of the button thats being called.
