ClusterODM Not Dividing Workload

I recently bought a DJI Phantom 4 Pro and now am running into some hardware limitations (mostly RAM). I have two very capable machines at home with 16 GB of RAM configured with ClusterODM, but when I use WebODM to create a new task (and set split, I’ve tried 50 and 230 on this 436 image task) it is only sent to one machine.

They are both online, per the web dashboard

Any ideas as to the problem? I have more RAM on the way for one machine, but still think ClusterODM may come in handy for large maps.
