nrf flash_fstorage

Question

hi. I use sdk16 and ble sample like kb or mouse. i want to save some data in ic. with flash_fstorage. 
 i see flash_fstorage example .it can use SOFTDEVICE_PRESENT for save. 
 but i use in ble sample, it can not save .it happen "app_error_fault_handler". 
 if i do not use SOFTDEVICE_PRESENT , flash_fstorage can save data .but if use SOFTDEVICE_PRESENT in ble sample, it can not. 
 why? please.
