The remote is always connected to the BN port. The light just denotes the out 1/out2 frequency being sent. The boost actually mixes both the out 1 and out 2 frequencies and makes it available at BN so you are covered. You can ignore the lights on the boost for now.
One other possibility is that the out 1 port has very high frequencies and out2 has low which is causing the out2 led to glowing whereas the out1 is not.
I wouldn’t worry. Boost takes care of both ports.
