This basically happened to me this cycle... low high high peak. I started on CD11 and got peak on CD14. I have a 30 day cycle and think I ovulated CD15 or CD16 which is typical for me. I believe peak is saying ovulation in 1-2 days so also on track there.
It’s only my second month using it so not sure what is normal. Did you just start using it this cycle or have you been using it and this varies from your current normal? Maybe you started testing earlier when you used it previously? Or, you may just ovulate earlier then you used to?
