Playing sample stops when another sample is selected

[R. Decline]

I'm sure this is just something goofy stupid I'm overlooking at 3am.
Normally I can play multiple samples at once. Tonight I decided to play with the factory glitch core beats as I hadn't really listened to them.
Hit play, tap one, it plays looping, hit a second one, and the first one stops, and the second one plays. Why won't it play both at once like it does for everything else I've used it for?

Are they set to the same choke group?

Edit: Oh the EXCL X/A/B/C ...yeah that seemed to be it. Set them to X from A and it's playing them at the same time it seems. Thanks.
