Unable to see the Resource - NIDs in the Add Relationships screen

Hi,

I am trying to setup a custom resource booking calendar to manage the availability status of my inventory.

This is the version of the dependent modules that I am using

Calendar 7.x-3.4+0-dev
Date 7.x-2.6
Resource Booking 7.x-1.0

I followed the instructions as per the attached README file provided.

However, I landed into an issue when performing the following step as per the instructions

A. Calendar of Resource Booking
3. Click on Relationships -> Add. Filter for Resource Booking and Add Resource NID

When I filter or resource booking the screen just shows one item for selection namely Resource Booking : Resource for selection. The other views are showing the Resource NID for selection. I am not sure if I am doing something wrong. Could you please guide me on the same? I am attaching the screenshots of both the view configuration as well as the relationship screen.
