Clear blue digital glitch...Maybe?

I bought a clear blue advance digital ovulation kit. On the first day I tried used it I used the kit 4 times in one day. The first two times at 9 and 10am I came up low fertile and the last two days of that day at 7 and 8pm I had a peak. Did it glitch because it skipped high fertility? Now the peak smiley face won’t go away.
