Agreement communication method updated after patching

Currently patching EBS from 12.2.5 to 12.2.7, and testing.  In a comparison of an agreement between each version, I noticed the following:

In 12.2.5, for this agreement communication method = None.

In 12.2.7, for the same agreement, communication method has both Fax and Email boxes checked.

Our profile option is set to pull communication method from the supplier site.  This supplier site has a communication method of Fax.  The site has both fax number and email address.

Even though I don't like it, I understand that if I update the agreement, it will re-default the communication method from the supplier site, even though I changed it and saved it.
