Babys due date on Glow

So I know the exact weeks arent as important as the due date, but I'm just confused is all.

Last pregnancy both my weeks and due dates lined up in both of my baby apps.

This time though it's just being weird.

I'm due December 5th 2020, so on one app it says that I'm 6 weeks and 5 days and on this app it says I'm 6 weeks and 3 days.

So to try to fix it I adjusted the due date to December 4th and now it wants to say I'm 7 weeks and 3 days.

It's probably the smallest "issue" on the planet. I'm probably just going to ignore it, but I just want to know how can I fix it?
