Lucky to have my flight from LAX-DOH now show Qsuites for late February, couldn't select middle seats to travel with companion initially. Called Qatar support who said the center sections could not be reserved until the day of the flight at the airport and they had no access to the seats. But can confirm contacting Qatar by tweet they were able to put us in the center seats, and now all center seats are open for me to switch around when checking online so I could move around to different rows if desired when previously they were all grayed out.
