Forecast line issue

Hi there,

I am trying to add a forecast for the following data, but I am having a bit of confusion over the forecast line I am getting.

The dataset I have contains location ID, date and number of sales.

Due to the requirement, I need to set the forecast length as one year / 52 weeks, seasonality at 52 and confidence interval at 95%. And when I do, instead of showing a forecast, it just replicates the previous year's result.

I guess my question is does that forecast look right? And if so, can you advise how I can fix this?

Kind regards,
