LPO Clock initialize WatchDog Problem

when I initialize the LPO Clock with the Processor Expert Default configuration (120kHz, LPO enable) then I am having problems with my watchdog. The watchdog is comming. But if I don't initialize the LPO Clock via the Processor Exper the watchdog will be fine.

The LPO clock register and the PMC register have the same values in both cases.

What is the Problem when I initalize the LPO clock ?

I use the S32K144.
