Cobra Pro Stops Charging When Asleep

I got a new Cobra Pro last night and set it up, and I’ve found that it does charge when placed onto the Mouse Dock Pro (though it takes a bit for Synapse to update it does at least charge and starts doing the breathing lights). The breathing lights keep cycling between standard lighting and the breathing, which I’m not sure if it’s meant to be doing or not. Either way, it continues doing the breathing yellow lights after the PC is put to sleep or turned off, so it seemingly still has power, but after the mouse goes to sleep it appears as though it just stops charging. I’m not sure how to fix it. It’s frustrating because my mouse charges partially, about 10-20%, then stops.
