Why hasn’t my glo calendar updated?

Glow predicted I would ovulate on January 18. I took an opk today and it was positive. I took a photo of the test and glow analyzed it and gave it a positive result. My calendar hasn’t updated though. It still says I’ll ovulate in 4 days. Shouldn’t it change and say I’m ovulating today?
