Hi Amplitude Team!

I would like to ask regarding the Amplitude Experiment. The case is that we have a sample size requirement of 57,000, two sided, and 95% confidence level. However when we wanted to analyse the result of the experiment and changed the Statistical setting to the required, the data showed that it “**needs more data to be conclusive” **and the statistical in the data is 0% when the supposedly performance is -1.8% (with MDE of 1%).

Is there any reason why this prompt is showing? Thank you!
