Midi problem with Walrus Audio M1 + D1

Good evening. I have a small problem. I have a Walrus Audio M1 V2 (modulation) pedal. I programmed it as follows:

Message 1:

release action -Programm change

Send Programm change - PC No.1

Message2:

release action - preset rename

Current active name - name

Message 3:

release action -Programm change

Send Programm change - PC No.1

Message4:

release action - preset rename

Current active name - name

etc…

and at the end these messages;

Message 27 :Press action - utility

                  manage preset message scroll

                  set number of message to scroll

                  number of message: 2

then:

Message 28: long press action - pos. 1 to turn the pedal ON

Message 29: Long press action -pos. 2 to turn the pedal OFF

Message 30: long press: toggle preset

all works fine. I can scroll through the preset and choose the desired one while being off , the with a long press action i turn it ON or OFF

Last week I bought the Walrus Mako D1 V2 (delay), so it’s the same Mako series as the M1.
So I copied the entire preset and applied it to the adjacent knob.

And then, surprise, the pedals stopped working properly.
As soon as the delay is copied, it messes up the modulation preset.
I don’t understand why.
