My sub-interface (200 Mbps BW statement) is inheriting the Tx and Rx load from my physical interface (300 Mbps statement). Is this some sort of bug? Is there a workaround? Anyone come across this?

I had not noticed this but when I think about it I find it pretty logical. If you think about it you have a physical GigEther interface that is operating as a trunk interface. The vlan sub interfaces are logical/virtual interfaces which are differentiated by a vlan tag number. But all tx and rx activity is done by the physical interface. Your sub interface is not doing its own tx or rx and so there is not a good way to report tx or rx at the sub interface level.
