Glitch sounds between pattern chain?!

Why is there suddenly glitch sounds between chained transitions and only between two patterns. Doesn’t happen when I switch the order around but if it’s in the correct chain order pattern 1 glitches transitioning into pattern 2! Tried resetting but the problem remains, what’s going on? It’s because I was pleased with how everything was sounding isn’t it? Really quite frustrating when you’re in a groove and this sort of thing happens, ruins the mood.

Could be something with the effects send delay settings?

Well now I feel dumb. I deleted everything out of frustration so I can’t confirm but that makes sense.
