The reason we brought up APFS is that when you downgrade, it may be a good idea to convert your startup drive back to HFS+ to ensure compatibility during the install process. Sierra has experimental support for APFS, though it may not be a good idea to try to use APFS with Sierra. High Sierra can support APFS on SSDs, but not Fusion or hard drives. APFS is currently only fully supported on all media types in Mojave. Mojave upgrades the startup drive to APFS, the new Apple File System. You can use the DiskMaker X app, and follow the instructions in Create a Bootable macOS High Sierra Install Drive with DiskMaker X.
