Currently the forecast grid is showing a calculation for revenue values based on the base value. This means that if your revenue value is captured in AUD and the system base currency is USD, any currency changes will impact what is shown in the forecast grid over time.

The forecast grid should just show whatever the actual value is NOT a calculation from the base field. This makes this functionality COMPLETELY USELESS for organisations that span countries which is very disappointing since the old goals feature experienced similar problems.
