Time Lapse photos?

🌸🌷🍄

This may have already been asked and answered so if it has, I’m sorry. I just went through my pictures I take weekly of my bump and uploaded them to my time lapse on my home screen. My problem is, they’re all a week behind. When I chose the first picture, I chose the correct date that matched it, for example: I’m 36 weeks today, 7/21. On my time lapse it says 35 weeks above the picture. Is there any way to change this so it’s right? It’s throwing me off with the rest of the pictures.
