typing into bible desktop, my keyboard is not the same as the one here

it's a uk keyboard I am typing on, though it seems to be the same whether I set windows to uk or us keyboard layout

My Ayin is produced by pushing square bracket.

My J produces a Tet

My F produces a Sin

My C produces a Tzaddik

My X produces a Het

Whereas the layout in the picture has Chet Tet Sin Tzaddik for J,F,C,X respectively.

That's different to mine.

Does anybody know what the explanation of that is?
