Invisible Power Pins on Parts B, C., . . . in Multiple Package Parts

Altazi

I have created a schematic symbol in Capture 16.6 by copying an existing dual op-amp symbol and making modifications for an op-amp package that has an exposed die pad (EP).  I would like to have the V+, V-, and EP appear on package A only, and not package B.  When I place package A, everything looks as it should - power pins present with short lines and numbers.  However, when I place package B, the previously-defined power pins 84 & 8) are invisible as desired, but  I can see the pin 9 line with no pin number.  I would like to have NO pin line showing.  As far as I can tell, the properties for pins 4, 8, and 9 are the same.  What is the trick to make this happen?

Thanks in advance.

    If you have selected the option of homogenous while designing the symbol then 5 pins will appear in both parts. Go for a heterogeneous package and define the power pins and IO in part A and rest in part B

    Thanks, Avenger Thanos.  This approach worked fine, and I can forge ahead.  However, I would still like to understand how the original part, which was defined as homogeneous, managed to have the two pins (4 & 8) disappear in package B.  THAT is the trick I'd like to know . . .
