the instance button was working and now its not I need help please

Have you just updated to macOS Tahoe? There is a small issue when using Logic, but unfortunately that's on Apple/Logics side so we are unable to fix that.

In Logic the area just above the plug-in name at the bottom has been made unclickable. This results in any button just above the plug-in name in our button bar becoming harder to access. There still is a small area at the top of the button that you can still click, but a large part of the button is unclickable.

We've reported this to Apple already, but unfortunately they did not release a fix yet.

Thank you if I’d known I wouldn’t have upgraded. Will you announce if they do this as it’s really handy to see the clashing EQs

You should still be able to access the instance list, but it's just a very small area to click.
