Glow Cycle Prediction

A

So my cycles as of recent have gone down to only 24-25 days, consistently for the last 4 months maybe 5. However, glow keeps predicting 28 day cycles? So it’s hard to tell when my predicted period is actually gonna come? How do I get glow to predict a 24 day cycle instead of a 28 day one when I am consistently logging a 24 day cycle for the last 5 months?
