What are the Facility Signature ID fields for that I see in the Mekorma Configurator's Logical Fields Category?

If you see the Facility Signature ID 1 and 2 fields in the Logical Fields category of the Mekorma Configurator, please do not use them on your check stub. These fields are non-functional fields and will not work for printing signatures with Mekorma MICR with or without Binary Stream's Multi-Entity Management(MEM).
