Why are some product variant prices not updating correctly?

I am adding a different price for each variant of a product with different sizes and colors. After uploading them, some prices were not adjusted to the changes I had made. For the most expensive ones, it shows the lowest price. I gave it some time to upload the changes as there are a lot of variants. I also closed the window and reopened it and there was nor change. Is there something I am not doing right, something I am missing?
