Octatrack MK2 as an Effekt Machine

Elektron Gear Octatrack
1

I like to use my OT as an Effect Machine for external sound machines (Alpha Base, Typhon), For that i use Track 1 and 5 as Thru Machines and all the other Tracks as Neighbor-Tracks. Track 1 use Input A B and Track 5 Input C D.
On all Tracks I use on both sides (1-4, 5-8) the same Effect cascade ), so that I have
8 Effects on each site.

Using the Scenes A and B to create different effect settings on each scene.

On Track 1 and 5 I use as Fx1 the Delay to create on scene 1-4 with the delay control function different Beat Repeat Effects.
But, I can not figure out how this work correctly?

Can somebody help me?

What is not working correctly?
What are your expected results vs what is actually happening?
