Path Based Routing is not working Properly

Describe the bug When i use pathType: ImplementationSpecific, it is being routed to one of the path I mentioned there(provided I don't give any paths explicitly), no matter what path i give to the host & when i use the pathtype: Prefix, it is always redirecting to alerta and not routing to grafana, even though i gave correct path

*To Reproduce** Steps to reproduce the behavior:
