Channel 3-4 react only to channel 4

After installing the new Software 5.12c I installed an ledcontrol 4 active. i connected all the leds to the controller.
but when i activate channel 3 nothing happens.

when i activate channel 4 the leds that are mentioned for channel 4 light up but also the leds that are mentioned for channel 3.

everything is checked several times for connection errors of the wiring.
because when i switch the cable form l1-2 with l-3-4 than everything works okay for the leds.

it seems like channel 3 is linked to channel 4 but is not operaratble separatly..?

when i install the simu-led bar.. in port L3-L4 there is an other strange thing if i control L3 nothing happens and when i control l4 only the red light will
light up..

Can somebody please help me

it did work before with the 4.08Software i had with evg-2af and simuled bar
