Hovertool display issue when using EdgesAndLinkedNodes

I am trying to display the node values (index,club) in karateclub network example as shown in the demos. However when I include the following line the node index and clubs displayed by HoverTool becomes ???

graph_renderer.inspection_policy = EdgesAndLinkedNodes()

How can I resolve this? The full code and screenshot is attached

import networkx as nx
from bokeh.io import output_file, show
from bokeh.models import (BoxSelectTool, Circle, EdgesAndLinkedNodes, HoverTool,
                          MultiLine, NodesAndLinkedEdges, Plot, Range1d, TapTool, ResetTool)

from bokeh.palettes import Spectral4
from bokeh.plotting import from_networkx

G=nx.karate_club_graph()

plot = Plot(plot_width=1200, plot_height=1000,
            x_range=Range1d(-1.1,1.1), y_range=Range1d(-1.1,1.1))

plot.title.text = "Graph Interaction Demonstration"

SAME_CLUB_COLOR, DIFFERENT_CLUB_COLOR = "black", "red"
edge_attrs = {}

for start_node, end_node, _ in G.edges(data=True):
    edge_color = SAME_CLUB_COLOR if G.nodes[start_node]["club"] == G.nodes[end_node]["club"] else DIFFERENT_CLUB_COLOR
    edge_attrs[(start_node, end_node)] = edge_color

nx.set_edge_attributes(G, edge_attrs, "edge_color")

# index =[];club = [];
# for index_val, node_name in G.nodes(data=True):
#   index.append(index_val)
#   club.append(node_name['club'])

graph_renderer = from_networkx(G, nx.spring_layout, scale=1.1, center=(0,0))

plot.add_tools(HoverTool(tooltips=[("index", "@index"), ("club", "@club")]), 
               TapTool(),
               BoxSelectTool(), 
               ResetTool())

graph_renderer.node_renderer.glyph = Circle(size=15, fill_color=Spectral4[0])
graph_renderer.node_renderer.selection_glyph = Circle(size=15, fill_color=Spectral4[2])
graph_renderer.node_renderer.hover_glyph = Circle(size=15, fill_color=Spectral4[1])

graph_renderer.edge_renderer.glyph = MultiLine(line_color="edge_color", line_alpha=0.5, line_width=3)
graph_renderer.edge_renderer.selection_glyph = MultiLine(line_color=Spectral4[2], line_width=3)
graph_renderer.edge_renderer.hover_glyph = MultiLine(line_color=Spectral4[1], line_width=3)

# graph_renderer.node_renderer.data_source.data['index'] = index
# graph_renderer.node_renderer.data_source.data['club'] = club

graph_renderer.selection_policy = NodesAndLinkedEdges()
graph_renderer.inspection_policy = EdgesAndLinkedNodes()

plot.renderers.append(graph_renderer)
output_file("interactive_graphs.html")

show(plot)

Also I would like to know how to make the box that shows up when clicking on a node persist when I have selected that node. Thanks!
