Jobs not getting scheduled

A lot of jobs for at least my lab which AFAICT should be being scheduled don't seem to be appearing, I can't see any sign of them when looking at the Maestro API viewer either. It all seems to be things triggered by kbuild-gcc-12-arm64-node-event - some things do appear (the baseline jobs and most if not all of the kselftest jobs.

For example we have:

- job: ltp-syscalls
event: *kbuild-gcc-12-arm-node-event
runtime: *lava-broonie-runtime
platforms:
- stm32mp157a-dhcor-avenger96

- job: ltp-syscalls
event: *kbuild-gcc-12-arm64-node-event
runtime: *lava-broonie-runtime
platforms:
- bcm2711-rpi-4-b

The 32 bit job appears in my lab, but I can't find the 64 bit one. The baseline jobs do however appear:

As do some ksefltest jobs such as:

https://api.kernelci.org/viewer?node_id=685f7ef85c2cf25042ece890

which is triggered by:

- job: kselftest-timers
event: *kbuild-gcc-12-arm64-node-event
runtime: *lava-broonie-runtime
platforms:
- bcm2711-rpi-4-b
- bcm2837-rpi-3-b-plus

which appears to have an identical event and runtime specification so I'd expect to be triggered at the same time.
