Inaccurate fertile days

Hi, my cycle was 32 days when I first used glow because I was on progesterone (not anymore), but my regular cycles are usually 24-26days. This time was 22 days after failing to conceive but looks like my fertile days never shifted forward. My settings was 24 days. Please explain, there is just no way I am presumed to ovulate on day 18, that will leave about 4 days of lutheal phase.
