It may sound obvious but check that you’ve got the trigs set on the thru track. If it’s a one-shot trig then it’ll need re-arming. I’ve found as well that hitting stop once doesn’t fully stop the sequencer in the way those trigs need. Just tap it a few times to make sure that isn’t it.
From what I remember about the beat repeat style delay, set the Lock parameter, which might be in the setup page, to on and then with the delay ctrl trig setup the rightmost buttons’ll activate each tracks delay and the leftmost set the repeat time.
