Not getting expected result in exercise 3.1

I’m unable to get the expected resulting rviz screen for exercise 3.1 (see attached screenshot)

Here I have expanded the errors shown

Hi,

change the fixed frame in RViz Display from map to odom.

Wasn’t able to change the fixed frame in RViz Display from map to odom. The drop-down list of options was not there.
I ended up signing off for a couple of hours and relaunching everything after my session timed out and the problem went away.
