Price Book error when reconfiguring Favorites from a Transaction

Summary:

When a Favorite have been added to a Transaction, the configuration can not be reconfigured without giving this error:

"The value _default_price_book is an invalid menu entry for the attribute with variable name _price_book_var_name."

Also the configuration are lost, so every configurable attribute has lost it value.

Content (required):

Price Books are not enabled on our environment.

Looking at the Favorites the "Price Book" field is "Base Price", but if reconfigure via the Action menu, this changes to blank.

It seems like we are missing something in our favorite setup!
