Scene Recall Filter for Input Patch does not work

I‘m playing with the latest firmware V1.5.4.

I wanted to save scenes for switching between USB Inputs for virtual soundcheck and others for switching between local IO or SLink. For each of the scenes I set a recall filter where I blocked all except Input Patch.

Although I saved each scene correctly with the Inputs patched appropriate, recalling them does nothing. Input patch remains as it was before recalling.
No global filters set at all.

When I also allow „Preamp“, it works…

I think this is not as it is supposed to work…

since you switch between “preamps” and other inputs I guess you have to enable the preamps to make it work…

it is not simple to configure this…

I understand what you mean, but it’s a little bit misleading…
