Ethernet expansion card not working on all ports

Hi there,
I’ve recently noticed, that the ethernet card doesnt work on the upper 2 ports (1 & 4). The 2 LED’s are on with the red one blinking slowly.
Is this a problem with the USB4.0 spec or a hardware issue?

Mine works fine in port 4, rear right.

I don’t usually use those ports because I use them for usbC and charging, but just tested and it works fine in them just like any other place.
