Success!!
Here's what I had to do...
Step 1
Go to the irons page 1 of 4 (shows the Ping G-10 Irons 3-PW); click and drag these into my bag;
3 thru 9 go into the bag (still no PW... had the exclamation point where the PW should have been)
Step 2
Go to the irons page 4 of 4 (also shows the Ping G-10 irons 3-PW); click and drag into my bag;
this time only the PW went into the bag
I now have the complete Ping G-10 iron set by doing the above two steps
Saved my changes and everything looks good.
