Hello Mr. Steven Rubin,
Thank you for your reply. I have been using the Electric in teaching for
many years. Many of my students usually do not notice the missing nodes
when making wires, like in the below image:

Therefore, I have to ask my students to do the Hierarchical DRC on a
schematic. Doing this function on a schematic can help them fix their
mistakes quickly.
So, I will tolerate this error, and I will just consider it a warning.
Thank you very much for your help.
Best regards.
