App is being wonky

Vee
So, my cycle is always 29 days and I usually O on CD18. I'm pretty sure I O'd on CD18 this month too. Today is CD27, AF due in 2 days. This morning I logged my bbt and then Glow moved my Fertile week saying that I O'd two days ago and extended my cycle to 37 days. So weird!! 
​Also, I REALLY do not like the new bbt chart. I think it is not professional looking and the data clearly cannot even be contained in the chart. I personally prefer the FF charts.
