google 1.10.2
upc/isbn mod installed - ISBN/UPC/EAN set to true in google config

After several hours on going back and forth with versions and fixes, I finally have been able to upload a feed to google succesfully.

I have 1,000 book products in critical warning that may get us suspended!

ISBN will not populate in the feed. It's in the googlefroogle.php files and I have pasted hundreds on the product pages. Anyone run into this before? UPC is working fine?!

Populating and Good:
MPN, Brand, UPC
