Logic Pro Drum Sounds only switching individually

I'm trying to add some drums to a song, but when I'm trying to browse the premade sets in the library (and consequently click on one), it'll only change the piece of the kit I have selected in the pattern region menu!

I swear i've clicked every button in the pattern region menu trying to figure this out, I have no idea what the problem is. Help would be appreciated soon, I'm on a time crunch :(
