Views Nodes Not Configurable in 5.3

As my username indicates, I’m an absolute beginner with KNIME. While going through Chapter 3 of KNIME Beginner’s Luck, I am trying to do the Scatter Plot exercise that begins on page 100.

The problem is that when I open the Scatter Plot node’s Configure window, it’s blank. The same is true for all the default views nodes. The nodes under Views > JavaScript do show me their their Configure windows, just not the ones under Views. In the screenshot, the nodes that show me blank configuration windows have been circled.

I’m using KNIME 5.3 on Windows 10. What do you think may be going on?
