FLL and PLL Disabled in BLPI mode

It's to my understanding that in the Bypassed Low Power Internal, the FLL and PLL are disabled. However, when I set the clock configuration I get a warning:

Warning: The PLL/FLL clock value is 0 - the clock is disabled. (Clock frequency [MHz])Cpu/Clock frequency [MHz]Processor Expert Problem

 

So, what's the actual problem with disabling both? Why am I getting this warning? BLPI mode is the only mode that allows me to use Very Low Power Mode, which is the purpose in using that as opposed to other modes. This is the only clock configuration.
