Unable to see BPM capability when KIE server is deployed on WebSphere, process definitions are not loading

Issue

The kie-server instance deployed on WebSphere throws exception "Process definitions cannot be loaded. Check if jBPM capabilities are enabled on remote KIE-SERVER"

Checking the server capabilities on this server instance gives the following response:
