MPC5744P FCCU Timeout Functionality Issue

I'm trying to configure some NCFs to have timeout functionality.
I configured 4 NCFs (7, 8, 10 and 12) with different configurations
7 >> no reset & timeout enable
8 >> short reset & timeout enable
10 >> long reset & timeout enable
12 >> Eout & timeout enable

and in the control tab (changed the timeout to be 65535)

then i generated code for this configurations and used it with the following sequence:
1- calling FCCU init function and passing these generated structs to it.
2- reading the NCF_TO register to ensure that it has 65535 value in it.
3- injecting a fault for one of the configured NCFs (7, 8, 10, 12).
4- I notice immediate reset without any waiting for timeout.

as I understand it shall enter Alarm state and wait there for specific time (the configured timeout) then enters Fault State.
what I see is that it enters fault state and perform reset immediately.

any ideas how to solve this?
also if there is example, that would be very helpful.
