Simulink For each with nonvirtual bus

Hello I am trying to refactor some old Simulink models and I am stuck with a problem:

I have a nonvirtual Input bus which I want to use in a for each block. However this seems not to be possible. My workarround is that I have a bus selector and a mux in front and a deumx and Bus creator at the end (see image)

this works fine. However, when I Connect the output to the bus again and compile the for each block seems to create only a single scalar output... (see image)

It has to do something with the for each block! How Do I have to specify the for each block in this case??

Glad for your help.
