The dynamic wallpaper doesn't work well

Hi there!

My name is Pagna. I am new with Apple products. Currently I have MacBook Pro with Big Sur and I'm trying to play around with wallpaper. I have seen that the dynamic wallpaper was awesome! For better experience, I have downloaded some dynamic wallpapers from the http://dynamicwallpaper.club. My problem is the dynamic wallpaper that I have downloaded doesn't change through the day unlike the original one. I know that my issue is not important but if someone can spare some time to guide me how to fix this would be a big gift for me! :)

All the best!

Pagna
