Rumlog logbook band = ???

[W9VQ]

I worked the Illinois QSO Party this past weekend and Rumlog performed flawlessly as usual, but at the end of the contest I noticed that although the Frequency column properly showed the frequencies in KHz, the Band column would show just three question marks, ???. So it will show 7,241.0 KHz, the Band column shows ??? I can not figure out why that occurred on 50% of the contacts, nor can I find a way to change it to the proper band. Anyone else ever see this behavior? Norman W9VQ
