Patterns disappearing

I’ve just began experimenting with GA5se. I’m sure it’s something that I clicked on but… now, when I load up a kit with pattern I seem to be missing some of the patterns. Before, the pad would show Intro 1, Intro 2 etc. Now it might only show Intro 3, Intro 4 (where 1 and 2 should have been). Also, where I would normally have Main 1, 2 etc Main 1 is missing and my first option is Main 2 (where main 1 should have been… There are no additional Group buttons (I checked that).
