Went to recreate a Minimal drive configuration on an 8 GB flash drive that formerly was configured by TTP 11 with the equivalent configuration. It failed on the first step, repartitioning the drive, leaving it unformatted. Disk Utility on the other hand was able to create a GUID partition with an MacOS Extended Volume. Tried again to create Minimal Profile drive with no success. Computer is running macOS Mojave 10.14.6. Looks like a bug in TTP 12.
