You actually have to hover over the "Delay", because the Seed is actually the Method 1 Frame 1 Seed of that PID (all PIDs can occur on frame 1, they just have to be valid seeds).
It's something you could use if you had AR codes (freeze that in the seed position and the pokemon will be that IVPID), but that's shady!
If you press "shift", you'll get another seed and another delay. Just hover over delay again to get your new seed.
