Custom button on edit page only

Hello,

I added a custom button to the Account edit page. It does not show initially unless i do additional refreshes to the page. If i add to the button to the Account section as well, the button shows up correctly on the Edit page without the need to refresh.

I only want it to show up on the Account edit page. How do i do that?

Thank you!
