Opportunity Probability $

Before upgrading to SuiteCRM 7.9, I had opportunity probability $ as a selectable column in reports.
After upgrading, my reports stopped working. Discovered that if I remove Opportunity Probability $ column, it started working but then, that column is no longer availabel to select in the list of opportunity fields.
How can I get Probability $ back?

Probability $ = Opportunity $ x Opportunity %


Is your system in plain English, or are you using a Language pack? Which one?
