Can someone please help me? CLEARBLUE ADVANCED DIGITAL Ovulation test

I got PEAK fertility 2 days ago & on this monitor thing it stays for 2 days as a smiley face

I took another test 2day and got another PEAK fertility smiley. Which lasts for 2 days. So apparently this clearblue advanced digital ovulation is saying I'm peak fertility for 4 days? How does that happen?

And according to glow and ovia I'm done with my fertility window as of today.

I thought you only get peak fertility 24-36 hrs b4 ovulation? But somehow I got it on 2 different tests?
