Different seasonality for the same month prophet #2608

I have a case when only monthly seasonality and the trend are used by prophet to build future forecasts. However, the additive seasonality terms in the output are different for the same month of a different year. Even though the forecasts turned out to be rather accurate, I would like to get the explanation ofn how exactly prophet calculates additive terms. Thank you!
