Missing HW Signal Connections

Hello
I have a Problem with DAVE 4

I Used to setup a Timerfunction. I have read the manual and there is written i need to use the ISR together with the Timer (CCU4).
And this way i need to couple those Signals to trigger a Interrupt when the timer has finished its job. (All things according to the Manual)
I done it stepp by step but now im stuck--> The HW Signal Connection cant be set and i dont know how to fix that.

Here is a Picture of the HW Signal Connections

Can Someone Help me?
