I recently flew on QR economy, 4 sectors, under a BA booking.
Seat selection (free) was available on 3 of the 4 flights, the 4th, due to it being on the lowest fare, seat selection was only available as an additional charge, so it sounds like your fare for whatever reason does not come with free seat selection.
I must add that I did a lengthy investigation and Bronze/Ruby benefits for free seat selection at-7days do not apply on QR operated flight and also that you cannot see seat selection on any other OW sites/apps other then QR in my experience.
