I couldn’t reproduce these 3; they work correctly for me
For me, this almost works correctly - I get taken to the next number instead of the correct one (e.g. if I click on 2, then the back up button, I get taken to where 3 is).
EDIT: Actually, this works correctly for me, it’s just that the number is at the very top of the screen, obscured by the top nav bar, which makes the next number often show up in the middle.
I also confirmed that the anchor link is the correct number.
This is browser behavior, so this is difficult/finicky to change - you’d have to detect an anchor movement and scroll it a bit further up or move the anchor a few lines up. And the vertical distance may be different depending on your Views settings, as well as your device width.
Might be a “won’t fix” as such 
This I could reproduce, looks mostly the same as your screenshots (my font size looks smaller though).
Seems like there’s a layout element missing.
EDIT: this looks normal on a large screen on desktop, but if I make the window smaller, it also reproduces on desktop.

EDIT: Also had the same results - could only reproduce the last one - on desktop:
