The selector issue is very visible in your video still: you can see black pixels at the top of the selected number where it shows the selector background, but none at the bottom because it's misaligned and the selection bubble is slightly outside its box.

Edit: zooming in closer it's maybe not outside the box at all, but there's some odd aliasing artifacts or something making the space above the highlight look bigger than the space below.

Honestly I don't think it makes it any better if the Unicode text is theoretically centered; the fact that there's zero separation between the options, and such poor spacing that it's difficult to tell and feels awkward either way is still terrible design.
