Basically for some pins the name of the pin end up ... wrong, it uses the name of an inside net inside.

Theses are the GDS and LEF ( viewed in klayout ) written by magic.

`pad_uio_oe_n_buf_I[2].z` should be `pad_uio_oe_n[2]`

```    - pad_uio_oe_n[1] + NET pad_uio_oe_n_buf_I\[1\].z + DIRECTION OUTPUT + USE SIGNAL
      + PORT
        + LAYER met4 ( -150 -500 ) ( 150 500 )
        + PLACED ( 28980 219820 ) N ;
    - pad_uio_oe_n[2] + NET pad_uio_oe_n_buf_I\[2\].z + DIRECTION OUTPUT + USE SIGNAL
      + PORT
        + LAYER met4 ( -150 -500 ) ( 150 500 )
        + PLACED ( 23460 219820 ) N ;
    - pad_uio_oe_n[3] + NET pad_uio_oe_n_buf_I\[3\].z + DIRECTION OUTPUT + USE SIGNAL
      + PORT
        + LAYER met4 ( -150 -500 ) ( 150 500 )
        + PLACED ( 17940 219820 ) N ;```

The above is the `PINS` section of the DEF and you can see how it's written (and it's the same for all the `pad_uio_oe_n` signals but only that one has the issue.

As you can see in the `GDS` view, there are two labels that end up on the pin area due to the geometry I guess ... ?

<@U016HU5HK8V>:  I'm pretty sure this is the same error I was looking at recently, so it's on my radar.  I recently changed a setting to allow all labels in a design to be output to the .ext file;  if they belong to the same net, they are put in an "equiv" statement.  Somewhere in the processing, a port can lose port status, and then it can get exchanged for any other label on that net.  I have not yet figured out how the port status flag is getting cleared.

There is an "extract" option that disables the "equiv" statements---you might try "extract no aliases" as a workaround.
