My viewport shortcuts have suddenly moved to the num pad? ( pulling my hair out)

Hi All,
My viewport shortcuts (1,3,7 etc) have moved to the numb pad and I cant reset them as blender see num pad 1 ect as the default.
I’d like to restore them to the normal top row numbers.
I can emulate number pad as a quick resolve, but then in edit mode 1,2,3 no longer select, but just move the camera.
if I try and adjust the keymap say for front view, select the key enter option and press 1 then save prefs it has no effect and my only choice is to reset to numpad?
I’ve recently installed box cutter and hardops, don’t know if that will effect it?
Any help would be great
Cheers
B
