10/4/2017 Topic: Can't change Next Check Number cbounds

I'm using PrintBoss with QuickBooks Enterprise 2016. This problem just started today. When I'm printing a check, the last step is always to "Confirm Next Check Number" within PrintBoss, to ensure that the number matches with the QB check number. But it suddenly won't let me change the number within this box. It shows what it thinks is the next check number and prints a check with that number, even if I hit "close" instead of "print". Before today, I was always able to change that number. I've restarted my machine, but don't know what else to try. Anyone else run into this problem?
