DNP3 - Latch On Working, but Latch Off Not

I am using TOP Server's DNP3 driver, and I'm able to send a Latch On command. However, when I send a Latch Off command, nothing happens in my device. Why is this?

This can happen because some devices require you to write to one bit in order to send a Latch On command, and another to send a Latch Off command.
 
Our team experienced this with an SEL device requiring a write of 1 to bit 5 to send a Latch On command, and a write of 1 to bit 4 to send a Latch Off command. However, it is certainly possible that other devices from other hardware vendors behave like this, too.
This can be resolved on the hardware side by tying these commands to the same bit. We recognized that quantity of hardware can make it difficult, so you can issue two separate commands instead.
