nrfutil settings generate" gives different CRC value from what bootloader calculates. Besides, I used JLinkExe savebin to dump application from DUT and the calculated CRC matches bootloader's value. It looks like nrfutil is problematic.
macOS 10.14
SDK15
nrfutil version 4.0.0

Note:
1. app.elf & app.hex are generated by SES
2. setting_page.hex is generated by:
nrfutil settings generate --family NRF52 --application app.hex --application-version 3 --bootloader-version 2 --bl-settings-version 1 --no-backup setting_page.hex
3. app_dump is by JLinkExe savebin app_dump 0x26000 0x00010698
4. nrfutil settings display setting_page.hex shows:
Bootloader DFU Settings:
* File: setting_page.hex
* Family: nRF52
* Start Address: 0x0007F000
* CRC: 0x1AEE538E
* Settings Version: 0x00000001 (1)
* App Version: 0x00000003 (3)
* Bootloader Version: 0x00000002 (2)
* Bank Layout: 0x00000000
* Current Bank: 0x00000000
* Application Size: 0x00010698 (67224 bytes)
* Application CRC: 0x243A6A75
* Bank0 Bank Code: 0x00000001
5. crc32 app_dump gives 758d7b9e, which is the same as what I see when debugging bootloader
6. Verify in SES, both by elf or intel hex will pass
