Based on what I read at https://powerbi.microsoft.com/en-us/blog/describing-the-forecasting-models-in-power-view/ I suspect that the model used for the forecast is producing an error only when the data falls in a specific type of pattern. In other cases, the function it is applying does not have a problem. In our problematic cases, it must be choosing a particular forecast formula-of-best-fit that has a bug in it.
I opened a support ticket to address this.
