Upcoming invoices are lower than expected

After subtracting the free quota, my bill last month was $6.68. But my bill so far this month is $0.00.

I wonder if there is a change in the way the free quota is calculated, or is there something wrong with the billing system?

By the way, I recently changed the deployment from multiple apps to single app multi-process. I don’t know if it has any effect.
