so on my kemper output the spdif clock is set to 44.1 kHz is this okay?
Yes - when all other values are the same and that's how you described it so far.
so logic is set to 44.1 kHz, do i need to change the kemper and focusrite to 48khz and leave logic at 44.1?
No. Simple rule: All need to have the same value. If you change one you need to change all.
Maybe for the sake of your testing you can try to set all to 48Khz. Change it on the Kemper, change in the Focusrite and set up a fresh project in the DAW with 48KHz in the project settings.
