Blinkstick Nano gets stuck in mode 1

[geerlingguy]

I can successfully switch my Blinkstick Nano between modes 2 (controls top LED) and 3 (controls both top and bottom LED), and can do so at will:

blinkstick --set-mode 3
blinkstick random # both LEDs light
blinkstick --set-mode 2 # top LED turns off (bottom stays on)
blinkstick random # top LED lights (bottom stays at old color)
blinkstick --set-mode 3
blinkstick random # both LEDs light and have same color
blinkstick --set-mode 1 # top LED turns off (bottom stays on)
blinkstick random # nothing happens
blinkstick --set-mode 3 # stays in mode 1
blinkstick --set-mode 2 # stays in mode 1

Maybe I'm missing something here, but basically if I switch to mode 1 it seems to get locked up or something, then I have to unplug it and replug it before I can control it again.
