QWERTY keyboards on iPad

Two different iPads, both updated, both have English QWERTY keyboard. Why are the keys for numeric and changing language in reversed positions on each? It drives me up the wall, as when I move from one device to the other, I keep hitting the wrong key by mistake!! And I do that a lot, as I use Emoijis (on change language key) and brackets, numbers etc ( on the numbers key) very frequently…

Ignore info about my iPad, I think it’s found an older one, the two I’m referring two are both fairly recent ones
