Getting a catalytic code will not turn off after replacing catalytic converter and both O2 sensors

Like the title says. Along with a host of K-CAN codes, cant get rid of cat code. I have installed an aftermarket catalytic and sensors. After reading BMW's don't like them I spent the cash and got OEM. New gaskets, new sensors, still there.

Also have an alternator code, don't know if its related.

I find it's weird it's just the catalytic code. No O2 sensor codes, also on cold start, it thinks the catalytic is up to temperature (see pics).

I also replaced both vanos sensors. I read sometimes they affect it.

I'm at a loss, anyone?
