v1.11.0(ppc64le) - Default GitLab Runner image not picked by Runner instance creation

GitLab Runner instance creation fails on ppc64le with error: Deployment.apps <Runner-name> is invalid: [spec.template.spec.containers[0].image: Required value, spec.template.spec.initContainers[0].image: Required value] Similar issue created for above failure 143

However, runner instance creation is successful, if Runner image is mentioned explicitly on UI:

Update: Need to mention Helper image explicitly too. If not mentioned, initContainer picks up x86 image and the job pods fail at prepare environment stage.

@ggeorgiev_gitlab was there any recent update in source code due to which default images are not being picked up correctly for ppc64le? Any pointers would be really appreciated.
