in accordance with [https://docs.easyeda.com/en/SchematicLib/SchLib-Subparts/](https://docs.easyeda.com/en/SchematicLib/SchLib-Subparts/), I added subparts for a multi-gate digital logic chip.  The tutorial says "double click on each sub part in turn to modify the Pin Name and Number attributes."  But when I do that, I just get the entire part on my cursor for placement on the schematic.  What am I doing wrong?  I want to configure the subpart diagram, pin numbers and pin names so that I can place individual subparts on the schematic (e.g., flipflops, AND gates, etc) showing the pin numbers and pin names that I assign.
