Edit existing component / bug

I was trying to edit an existing component when I found this bug:
Component part number is Raspberry Pi B+ GPIO Male Shrouded Header
When I try to edit a pin label, the new label overlays the old label, and the label on pin one disappears.
Sometimes the new label is applied elsewhere.
I tried with different components, easy to reproduce.

  1. on the schematics page, double click a component
  2. In the dialog displayed, click the “edit manually” (top, centre)
  3. On the Component Editor page, click “pins” on the right side panel.
  4. Click on the “edit” button, just under “pins”
  5. Change any pin name and save

I am new to Upverter, perhaps I am doing something wrong…?

Best to add labeled netlists rather than modifying the actual pins on the header.
Leave the header alone, and goto the left side, and pick one of these (shown in picture). Give these a unique name, no spaces. For instance, GND for ground, VCC for power etc… The name is important.
Nets with the same name are “connected”.
