have you ever had this? Port 4 yes / Port 5 no

Hi,
my story actually starts here https://forum.opnsense.org/index.php?topic=37114.0 in the meantime many things are working und my knowledge is fast increasing ... but still I'm having a problem which I cannot understand.

Setup:
opn subnet (vlan 40) 192.168.40
to
Cisco SG200-26 Port 25 in (Trunk: 10T,20T30T,40T50T100T,1PVID001): Port 8 out (Trunk 30T,40T,1001UP)
to
Cisco SG200-08 Port 1 in (Trunk 30T,40T1001UP): Port 2 out (Access 40U)
everything works!
By just connecting it to another pysical port (Port 8 on Cisco26 wich was copied from the working port 7) all vlans are gone.
the remarkable thing is that when connected on the working port 8 th switch registers itself in 192.168.1.x on the copied not working port 7 it registers in 192.168.40.x
Thats is the reason why its not working, But why?

Any hint / advice, whatsoever is highly appreciated.
Thanks
