Pressing a preset button switches state of other preset button (MC6 mk2 & Strymon Volante)

I have set up a bank to control the looper functions of the Strymon Volante.
Button A is handling record/splice/clear on cc49 with any value.
Button B is set up to disable/enable overdub with the following settings

Button C is set up to switch between halfspeed and normal speed/button F to double speed
Button D switches between forward and backwards.
Whenever I press C or D or F, the state of Button B switches to overdub when set to no overdub before…

What am I missing?

you’ve probably ‘clear preset toggles’ enabled (bank settings).
