Forcing usage for all GPUs

[xabbix]

When running what is considered by Hashcat smaller attacks, not all GPUs are being used. For example, I'm running a Hybrid attack (mode 6) and even though it contains a rather large number of passwords to be attempted, it still uses just one GPU:

Is there any way of forcing the usage of all GPUs?
