Error: "Update Opening Entries not Successful"

Problem
Error: "Update Opening Entries not Successful" when running Validity on Gain Loss Exchange Account

Environment
SFM

Solution
Create a Journal Entry between Bank/Cash and Unrealized Gain/Loss account using Local Amounts only (leave Foreign Amounts 0).

Cause
This is because a foreign amount of any value (in this case .85c) can never equal to a local amount of no value (0.00c)
